ETHYLENEDIAMINE

Ethylenediamine, called Ethylenediamine in Turkish, is a short-chain aliphatic diamine containing two primary amine groups. Its chemical name is ethane-1,2-diamine or 1,2-diaminoethane; It has CAS No 107-15-3, EC No 203-468-6, molecular formula C₂H₈N₂ and molecular weight approximately 60.10 g/mol. The molecule is H₂N–CH₂–CH₂–NH₂.
Ethylenediamine is of primary importance as a chemical intermediate in industry. It can be used in the synthesis of chelating agents, amine-derived resins, polyamide chemistry, epoxy hardener systems, anti-corrosion intermediates, fuel/oil additives, textile auxiliaries, and in the production of various agricultural chemicals. In BASF product information, Ethylenediamine is particularly associated with chelator synthesis, bleaching activators, crop protection chemicals, polyamides, and polyurethane chain extenders.
Ethylenediamine is not the same product as EDTA. Ethylenediamine's two amine nitrogens can form coordination with metal ions; however, EDTA is the separate, often more potent chelator, containing numerous binding points and four carboxylate groups. Ethylenediamine may be one of the building blocks used in the production of EDTA; it cannot be used as a direct substitute for EDTA.
Commercial Ethylenediamine is a hygroscopic liquid with a pungent amine/ammonia-like odor, mostly colorless to slightly yellow. Miscible with water and alcohol. A boiling point of about 116–117 °C, a melting point of about 8.5–11 °C, a density of about 0.90 g/cm³, and a closed cup flash point of about 34 °C have been reported. Numerical values may vary slightly depending on the measurement method and grade.
Ethylenediamine is a hazardous industrial raw material. It can cause serious skin burns and eye damage; it can cause sensitization to the skin or respiratory tract and release flammable vapors. Therefore, it should be used in closed, controlled and properly ventilated systems based on manufacturer SDS and workplace risk assessment.
In the purchase evaluation, not only the CAS number; purity, water content, color, amine value, density, product stability, packaging material, application area and current TDS/SDS/COA documents should be examined together.

WHAT IS ETHYLENEDIAMINE?

Ethylenediamine is ethylene diamine that carries a –NH₂ group at each end of the carbon chain. The presence of two amine groups provides higher reaction and coordination diversity than monofunctional amines.
Chemical name: Ethane-1,2-diamine. Common name: Ethylenediamine, Turkish name: Ethylenediamine. CAS No: 107-15-3. EC/EINECS No: 203-468-6. Molecular formula: C₂H₈N₂. Molecular weight: About 60.10 g/mol. General structure: H₂N–CH₂–CH₂–NH₂.
Each primary amine nitrogen in the ethylenediamine molecule shows basic properties. It can react with acids to form ammonium salts. Since both amines can be protonated under favorable conditions, mono- and diprotonated species can form; their distribution depends on the ambient pH and companion ions.
Two amine nitrogen can bind together to the metal ion and form a five-membered chelate ring. This property makes Ethylenediamine an important ligand in coordination chemistry. However, metal complex formation in aqueous solution depends on the type of metal, pH, and the presence of other ligands.
Ethylenediamine is a strong basic reaction component; heat output can occur when mixed with acidic ingredients. Because amine-hydrogens can react chemically with epoxy groups, they can be considered as reactive hardeners in some epoxy curing systems or as an intermediate in the production of other amine hardeners.
Its bifunctional structure makes it possible to use diamine as a bridging or chain extender in polymer synthesis. However, Ethylenediamine's reactivity, odor, and hazard profile make modified amine or higher molecular weight derivatives preferred in many applications.

The reaction of one or two amine groups leads to a significant change in the molecular structure of Ethylenediamine. Therefore, when establishing product equivalence with monoethyleneamine or other ethyleneamine mixtures, chemical purity and component distribution must be verified.

CHEMICAL STRUCTURE AND MOLECULAR PROPERTIES OF ETHYLENEDIAMINE

The primary amines at the two ends of ethylenediamine are attached to the small and flexible ethylene backbone. Each amine group contains a basic center that can receive protons and two N–H bonds that can react.
Thanks to its two amine groups, Ethylenediamine can participate in the reaction from a single end or from both ends in different reactions. Salt forming with acids; condensation with aldehydes, ketones, and suitable derivatives; nucleophilic ring opening to epoxy groups and amide formation with carboxylic acid derivatives are important chemical behavior examples.
During coordination to metals, nitrogen atoms act as electron pair donor centers. A single molecule of Ethylenediamine can act as a bidentate ligand, providing two binding sites around the metal. Some coordination complexes in which three Ethylenediamine ligands are located around a metal are common examples in the literature. The actual structure of the complexes depends on the type of metal, the oxidation step, the pH, and the solvent.
Ethylenediamine is different from EDTA: Ethylenediamine has amine nitrogens, but the four carboxylate arms in EDTA are not. Therefore, the chelating behavior and usage dose of Ethylenediamine cannot be considered equivalent to EDTA.
The short molecular structure and the ability of amine groups to form hydrogen bonds ensure high compatibility with water. This can be useful for easy dosing in aqueous processes; however, due to its basicity and corrosive character, it does not mean that it is directly suitable for every aqueous mixture.
Ethylenediamine should be treated as a reactive amine that can absorb ambient humidity and acidic gases from the air. These interactions can affect purity and some quality parameters during storage. It is important to use sealed packaging and limit moisture/carbon dioxide exposure.

Key properties at the molecular level:

To be able to coordinate with metal ions from two points

To be able to react with epoxy groups

To be a chain extender or intermediate in polymer synthesis

To be able to mix completely with water

Showing high reactivity and exposure sensitivity due to its low molecular weight.

HOW DOES ETHYLENEDIAMINE WORK AT THE MOLECULAR LEVEL?

The working mechanism of ethylenediamine varies according to the application. In chelator synthesis, the molecule forms the ethylenediamine skeleton to which carboxymethyl groups are attached. In coordination chemistry, it acts as a ligand by giving electron pairs to the metal ion with its two nitrogen.
Protonation of amines is important in acid-base reactions. The addition of an acid directs the amine's electron pair to proton bonding; the ionic character of the molecule changes. Solubility, volatility, pH, and compatibility with other components may be affected as a result of this.
In epoxy chemistry, the primary amine group can open the epoxy ring. The reaction of an N–H bond results in the formation of a hydroxyl group, and the amine can still be active for the second reactions. As the reactions progress, a three-dimensional cross-linked network can occur. Since low molecular weight Ethylenediamine carries rapid reaction and high exotherm potential, it should not be assumed that it is suitable directly for large-scale mixtures or thick castings.
In polyamide synthesis, the reaction of amine functions with organic acid or acid derivatives helps to form the polymer chain. In polyurethane applications, chain extender chemistry can take place in appropriate systems.
In corrosion inhibitor applications, Ethylenediamine is often important not directly as a universal corrosion inhibitor but rather as an intermediate in the production of protective derivatives and functional amine additives. It should be noted that basic Ethylenediamine may be incompatible with certain metal surfaces or alloys.
The main variables that determine the performance are: Ethylenediamine purity, water content, pH, reactive group ratio, process temperature, solvent, metal type, other amines and target application of the product.

IN WHICH SECTORS IS ETHYLENEDIAMINE USED?

Production of various chelators in the chemical industry

Synthesis of EDTA and other aminopolycarboxylate derivatives

Synthesis of plant protection chemicals

Intermediate for detergent and bleaching activators

Polyamide resin production

Epoxy amine hardener systems and intermediates

Chain extender chemistry in waterborne polyurethane dispersions

Printing ink binder resins

Hot melt and heat seal adhesive polymers

Intermediate for lubricant and fuel additives

Anti-corrosion additive derivatives

Textile auxiliary chemicals

Coordination compounds and catalyst research

Laboratory analytical/research applications

BASF's product portfolio specifically identifies Ethylenediamine for chelators, bleaching activators, plant protection products, polyamides, and related intermediates. Some of the applications here do not use Ethylenediamine directly, but rather the final chemical product derived from Ethylenediamine; this distinction must be maintained in the design of procurement and formulation.

CHELATING AND COORDINATING CHEMISTRY APPLICATIONS OF ETHYLENEDIAMINE

At the heart of ethylenediamine's importance in coordination chemistry is its ability to co-bind two neighboring amine groups to the metal atom. Such two-point bonding can provide different complex stability than single-binding ligands.
Ethylenediamine itself is a bidentate ligand. EDTA, on the other hand, is an aminopolycarboxylate chelator with many more coordination regions derived from the Ethylenediamine backbone. Therefore, a percentage substitution between direct Ethylenediamine and EDTA for hard water control, trace metal binding, or cosmetic stabilization is not recommended.
In coordination complexes, the concentration of Ethylenediamine, as well as the pH and metal/ligand mole ratio, are important variables. Complex formation may result in different color, spectrum, or solubility behavior depending on the metal type. However, it should also be taken into account that Ethylenediamine may create precipitation or undesirable complexation with some metal ions.
In the chemical industry, Ethylenediamine can be used as a starting agent in the production of aminopolycarboxylate chelators. These manufacturing processes require special reaction control; it is not the same as a general formulation trial.
In laboratory tests, metal type, metal concentration, initial pH, pH change, temperature, ionic strength and Ethylenediamine purity should be recorded.

EPOXY, POLYAMIDE AND POLYURETHANE APPLICATIONS OF ETHYLENEDIAMINE

Because Ethylenediamine transports four amine-hydrogens, it can theoretically participate in multifunctional epoxy curing reactions. The active hydrogen equivalent weight of pure Ethylenediamine is approximately 15.03 g/eq; however, the epoxy equivalent weight (EEW) of the resin must be known in order to calculate against the actual epoxy resin.
To determine the Ethylenediamine ratio in an epoxy system, it is not enough to look only at the mass percentage. Reactive group stoichiometrics, purity, availability of other hardeners, exo-thermic heat release, film or casting thickness to be applied, humidity and processing time should be evaluated together.
Because Ethylenediamine is a low molecular weight, volatile/corrosive, and very reactive amine, modified amine hardeners or more controlled amine adducts can be used directly in place of pure Ethylenediamine in many practical epoxy systems. The general production recipe for mixing a large amount of resin with pure Ethylenediamine should not be given.
The diamine function of Ethylenediamine in polyamide resins contributes to the creation of polymer architecture through condensation reactions with suitable di- or polycarboxylic acid derivatives. Polyamide resins can be used in applications such as adhesives, ink binders, and coating systems.
In waterborne polyurethane dispersions, Ethylenediamine can be used as a chain extender in the appropriate pre-polymer chemistry. Free Ethylenediamine and the final polyurethane product do not have the same hazard profile. The final product should be evaluated separately in terms of residual Ethylenediamine and legislation.

CORROSION, LUBRICANT AND TEXTILE APPLICATIONS OF ETHYLENEDIAMINE

Ethylenediamine may be a reaction intermediate in the production of certain anticorrosion chemicals. Its amine functions can be used in the formation of functional groups that can interact with metal surfaces. However, it is possible that pure Ethylenediamine may be corrosive or unsuitable in certain metal environments; hence, it should not be considered as a general corrosion inhibitor on its own.
In lubricant and fuel additives, Ethylenediamine derivatives can be converted into functional compounds that affect friction, dispersion, or corrosion behavior. The primary use in these sectors is mostly in the form of production of Ethylenediamine-derived derivatives rather than direct Ethylenediamine dosage.
In textile auxiliaries, Ethylenediamine can be an intermediate in the production of chemical products with polymeric or surfactant properties. The final formulation to be applied directly to the fabric should not be confused with the chemical synthesis raw material.
In each application, the amount of residual amines, odor, exposure, product compatibility, and the specific legislation of the target sector should be examined separately.

IS ETHYLENEDIAMINE USED IN FOOD, COSMETICS AND PHARMACEUTICAL APPLICATIONS?

Pure technique Ethylenediamine should not be considered as a direct food additive, cosmetic preservative, or consumer product ingredient. It is not recommended for general products targeting direct skin contact due to its corrosive and sensitizing nature.
The use of ethylenediamine as a chemical intermediate does not mean that a different molecule produced from it has the same status in cosmetics, food, or medicinal product. The regulatory decision on the use of an ethylenediamine-derived compound should be made based on the derivative's own chemical identity and purity certificates.
In pharmaceutical manufacturing, Ethylenediamine or Ethylenediamine derivatives can pass as synthesis intermediates. However, industrial Ethylenediamine grade should not be assumed to have direct pharmaceutical excipient status. Each use requires GMP, residual solvent/reagent controls, and final product evaluation.
Polymers derived from Ethylenediamine may be present in food contact packaging. This does not mean that free Ethylenediamine is suitable for direct food contact.

INDUSTRIAL APPLICATIONS OF ETHYLENEDIAMINE

The main functions of ethylenediamine in industry are:

Being a chemical building block with two amine groups

Being an intermediate in the production of aminopolycarboxylate chelator

Providing reactive amine function in epoxy chemistry

Joining diamine as monomer in polyamide production

Polyurethane is used in chain extender chemistry

Being a bidentate ligand in coordination complexes

To be used in the production of related lubricant, corrosion inhibitor and textile derivatives

Technical quality criteria are not limited to the percentage of purity. The amount of water, color, impurity profile, primary amine ratio, transportation requirements and packaging compliance must be monitored.
Concentration calculations for Ethylenediamine solutions containing water should be made based on the actual active ingredient amount of the commercial raw material. Since the mixing of Ethylenediamine with water may be exothermic, addition and temperature control should be carried out with appropriate laboratory procedures.

WHAT PROBLEMS CAN ETHYLENEDIAMINE HELP SOLVE?

Suitable diamine skeleton required for chelator synthesis

Ethylenediamine can be used as a basic building block with two nitrogens.

Investigating the coordination chemistry of the metal complex

Ethylenediamine is a ligand that can bind to the metal ion via two nitrogens.

A polymer needs a chain extension reaction

In suitable polyamide or polyurethane systems, diamine functionality can be evaluated for chemical reaction.

Examining amine reactivity in epoxy system

Ethylenediamine is an example of a theoretical reactive amine; however, it requires special attention in practical prescription design due to its rapid exotherm and high risk of exposure.

Derived lubricant or corrosion inhibitor chemical synthesis planned

Ethylenediamine can be the starting material for creating functional amine derivatives.

Ethylenediamine changes color or purity in storage

The effect of moisture and acidic gases in the air, packaging, storage temperature and contamination should be checked.

pH higher than desired in the aqueous system

Ethylenediamine has the character of a strong basic amine. The need for dosage and neutralization should be re-evaluated; it should not be forgotten that the reaction with acid may produce heat.

Amine odor or exposure problem

Closed system, local suction, appropriate transfer and transition to the appropriate product derivative should be evaluated. Removal of odor by masking alone is not a substitute for safety control.

THINGS TO CONSIDER IN THE USE OF ETHYLENEDIAMINE

The correct product name, CAS 107-15-3 and the grade being enameled should be verified.
Manufacturer TDS/SDS/COA documents should be examined together.
It should be taken into account that ethylenediamine contains two primary amine groups and can show high reactivity.
It should be taken into account that heat may be released during mixing with acids.
Flames, sparks, hot surfaces and ignition sources should be checked.
Suitable chemical resistant closed transfer systems should be preferred.
Ventilation and vapor exposure control should be provided.
Skin contact, eye splashes and respiratory exposure should be avoided.
Skin and respiratory sensitization is important.
Water content and amine purity should be verified.
Contact with moisture and carbon dioxide should be limited during storage.
Product appearance should be checked at temperature close to the melting point.
Compatibility with packaging and piping materials should be verified.
The type of metal and process corrosion should be tested.
In epoxy or other reactive polymers, the temperature rise and reaction rate must be measured.
Uncontrolled environmental discharge should not be made.
Dilution, neutralization, and other reactions should only be carried out with proper workplace procedures.

INITIAL FORMULATION APPROACHES FOR ETHYLENEDIAMINE

The following examples are not verified commercial product recipes, manufacturing instructions, or dosages for use. They are initial compositions by weight for comparison purposes only in controlled laboratory investigations. Ethylenediamine is a corrosive, flammable and sensitizing substance. Processes should only be evaluated in appropriately equipped laboratories, with a closed system and risk control in accordance with SDS.
In all recipes, the total percentage is calculated based on the mass of the raw materials in the formulation. Test elements such as metal coupons and analysis reagents are not part of the product formulation.

While the amount of sodium acetate varies, the total composition is completed to 100% with water.
Conductivity, pH, clarity, and storage appearance are compared.
If an additional analytical reference without ethylenediamine is required, it is prepared in separate test sets.
This system does not assume pH fixing or acid-base neutralization.
The suitability of the application can only be determined at the end of chemical compatibility studies with the actual target process.
If compatibility with different metals is required, metal coupons are tested separately; metal coupons are not included in the weight percentage of the formulation.

ALTERNATIVES AND COMPARISON OF ETHYLENEDIAMINE

When selecting an alternative to ethylenediamine, one should look at the amine functionality, molecular weight, reactive hydrogen equivalent, basicity, vapor pressure, odor, solvent compatibility, temperature, and hazard classification, not just the presence of two amine groups. Different ethyleneamines or diamines cannot be substituted in the same weight ratio.

ETHYLENEDIAMINE AND DIETHYLENETRIAMINE (DETA)

DETA is a higher molecular weight ethyleneamine containing three amine nitrogens. Ethylenediamine carries two primary amine groups, while DETA contains two primary and one secondary amine centers. Thus, the number of active hydrogens, basicity, reaction rate, and epoxy curing stoichiometry change. Ethylenediamine and DETA should not be replaced one-to-one by weight.

ETHYLENEDIAMINE AND TRIETHYLENETETRAMINE (THETA)

TETA is a member of the larger ethyleneamine family that contains four amine centers. The commercial product may contain mixtures of isomers in some cases. While ethylenediamine has a lower molecular weight, TETA differs in viscosity, volatility, reaction character and formulation effect. Epoxy applications require recalculation based on active hydrogen equivalent and ethylenediaminer grade.

ETHYLENEDIAMINE AND HEXAMETHYLENEDIAMINE (HMDA)

Hexamethylenediamine carries a six-carbon chain between two amines. In ethylenediamine, the chain in between is two-carbon. HMDA is especially important in the production of some polyamides. Changing the chain length affects crystallization, melting, solubility and polymer mechanical properties. It is not appropriate to consider two diamines as direct equivalents.

ETHYLENEDIAMINE AND ETHANOLAMINE

Ethanolamine contains one amine and one hydroxyl group, while Ethylenediamine carries two amines. Therefore, its acid-base, reaction, and polymerization functions are not the same. Ethylenediamine is not diamine directly equivalent to ethanolamine in a synthesis that requires its use.

ETHYLENEDIAMINE AND EDTA

EDTA is the higher functioning ligand containing carboxylate groups attached to the Ethylenediamine skeleton. Ethylenediamine is a small bidentate ligand; EDTA, on the other hand, is an aminopolycarboxylate chelator known for its multipoint metal-binding capacity. While EDTA can be a direct additive for metal control, Ethylenediamine is in many cases an intermediate for chelator synthesis. It cannot be substituted with the same amount of grams.

ETHYLENEDIAMINE AND PIPERAZINE

Piperazine is a chemical containing two secondary amine centers in a cyclic structure. Ethylenediamine contains two primary amines with open chains. Since the ring structure, functionality and chemical reactivity are different, the same synthesis and formulation performance should not be expected.

The exact purity of the product, the amount of water and the component distribution must be verified from the COA of the grade to be purchased.
In stoichiometry-sensitive applications like epoxy, analytical purity or active amine content is important. Water and non-reactive impurities can change the equivalent calculus.
Corrosion and packaging compatibility should be checked for product transfer safety.

STORAGE AND HANDLING OF ETHYLENEDIAMINE

Storage: It should be stored in tightly closed, chemical-resistant packaging recommended by the manufacturer.

Temperature: Physical change may occur in environments close to the melting point; it should be kept away from sources of extreme temperature and ignition.

Fire safety: The generation of flammable vapors should be taken seriously as the closed container flash point is approximately 34 °C. Appropriate explosion protection measures and equipment are used.

Moisture: Since it is a hygroscopic product, moisture absorption from the air should be reduced.

CO₂ exposure: Reaction with acidic gases from the air can alter quality; it should not be kept in an open container for a long time.

Acids and oxidizers: Must be kept separate from incompatible substances, and uncontrolled contact must be prevented.

Packaging: Metal, plastic, elastomer and seal compatibility must be verified with current manufacturer recommendation.

Transport: Ethylenediamine is identified as UN 1604; its corrosive and flammable hazards are considered in transport legislation. The packing group and full classification must be verified from the current SDS.

Contamination: Cross-contamination with other amines, acids, oxidizers or metal salts should be avoided.

FIFO: Batch-based stock management and retest tracking should be implemented.

ETHYLENEDIAMINE SAFETY INFORMATION

The safety of Ethylenediamine as a raw material is a high priority. In the International Chemical Safety Card and manufacturer safety information, it is reported that Ethylenediamine is a flammable, corrosive and sensitizing substance.

The main dangers are:

Severe skin burns

Serious eye damage

Allergic sensitivity to the skin

Respiratory sensitivity or asthma-like symptoms

Irritation of the respiratory tract when inhaled

Harmful/toxic exposure by ingestion or skin

Flammable vapours

Risk of reactions with incompatible chemicals

Concentrated Ethylenediamine should be used with a closed system, local suction, chemically resistant gloves, appropriate eye-face protection and other PPE determined by workplace risk assessment.
Recognizing amine vapor by smell does not indicate a safe exposure level. Odor masking is not a control method. Especially in sensitive workers, a reaction may be seen at low exposures.
Reaction with acids may release heat; preparation and transfer processes should only be carried out with proper facility procedures.
In case of eye or skin contact and respiratory complaints, emergency aid should be administered in accordance with the first aid instructions of the SDS.
Spills should not be released into the environment or sewage uncontrollably. Fire and spill response should be based on UN 1604 information and local emergency procedure.

WHAT TO CONSIDER WHEN BUYING ETHYLENEDIAMINE?

First, the target application should be clarified. Chemical purity and impurity expectations may be different for Ethylenediamine to be used in chelator synthesis and Ethylenediamine to be used in epoxy reaction or polymer synthesis.
Ethylenediamine, CAS 107-15-3 and target purity must be clearly written in the offer. It must be verified that DETA, TETA and other ethyleneamines are not mistakenly offered equivalents.
The required analysis documents should include purity, water, color, relevant impurities, and batch COA information. Proper packaging for storage, delivery temperature, and transportation classification are just as important as the price.
Due to the low molecular weight and chemical reactivity of ethylenediamine, the temperature control of the process, material compatibility, and operator exposure should be included in the purchasing evaluation. Two grades with the same CAS number may have different impurity profiles.
In the quotation comparison, not only the kilogram price, but also the amount of active Ethylenediamine, purity, packaging safety, logistics conditions and compliance documents should be compared together.

ETHYLENEDIAMINE – TECHNICAL SUMMARY

Ethylenediamine is ethane-1,2-diamine, which carries two primary amine groups. It has CAS No 107-15-3, EC No 203-468-6, formula C₂H₈N₂, and molecular weight of approximately 60.10 g/mol. The molecule is H₂N–CH₂–CH₂–NH₂.
Ethylenediamine is a small molecular weight, basic, fully miscible with water, and highly reactivity-bearing chemical intermediate. It is evaluated in chelator production, agrochemicals, bleaching activators, polyamide resins, appropriate polyurethane chain extension chemistry, and epoxy amine systems.
Ethylenediamine is not the same as EDTA. Ethylenediamine's two amine nitrogens can form bidentate coordination with metal ions; EDTA, on the other hand, is a separate chelator containing four carboxylate arms.
It is a colorless/slightly yellow, pungent-smelling liquid at normal temperature. It has a boiling point of about 116–117 °C, a melting point of about 8.5–11 °C, a density of about 0.90 g/cm³, and a closed cup flash point of about 34 °C. The theoretical active hydrogen equivalent weight of pure Ethylenediamine is about 15.03 g/eq.
Due to its corrosive, flammable, and sensitizing character, Ethylenediamine should only be used under appropriate industrial or laboratory control. For user and environmental safety, closed system, ventilation, material compatibility, and up-to-date SDS should be taken as a basis.
CAS, purity, water, amine analyses, color, impurities, packaging, and current technical documentation must be verified at the time of purchase. Trials in formulation titles are controlled laboratory research compositions; they are not validated recipes for commercial production or consumer use.
