DIETHYLAMINOETHANOL

Diethylethanolamine (DEAE) is a chemical compound with the molecular formula C6H15NO. It is used as a precursor in the production of a variety of chemical commodities such as the local anesthetic procaine. It can be reacted with 4-aminobenzoic acid to make procaine. DEAE can be used as a precursor for DEAE-cellulose resin, which is commonly used in ion exchange chromatography. DEAE can also be conveniently obtained from renewable sources. It is chemically stable and able to absorb carbon dioxide (CO2) from its surroundings. In solution, it can decrease the surface tension of water when the temperature is increased.

Diethylethanolamine (DEEA) is a colorless, hygroscopic liquid base combining the properties of amines and alcohols. It is soluble in water, alcohol, and benzene and it is combustible.

Diethylethanolamine is used as a corrosion inhibitor in steam and condensate lines. It is also used as a textile softener, an emulsifier in acid media, and a curing agent for resins.

N,N-Diethylethanolamine (DEEA), which can be prepared from renewable resources, represents a candidate alkanolamine for CO2 removal from gaseous streams. In this work, the reaction of CO2 with aqueous solutions containing N,N-diethylethanolamine (DEEA) was studied in a stirred cell reactor with a plane, horizontal gas−liquid interface, in the range of temperatures 298−308 K. The DEEA concentration in the aqueous solutions was varied in the range 2−3 kmol/m3. The liquid-side mass transfer coefficient and a combined parameter comprising the reaction rate constant and the diffusivity and solubility of CO2 in DEEA solutions were evaluated. The effect of the addition of piperazine (PIP) as a possible absorption activator was studied, and it was found that even with a small amount of PIP (0.1 kmol/m3) added, the CO2 absorption rate increased.

DEAE is a chemical product that has neutralizing and oxygen scavenging characteristics, and is used as a corrosion inhibitor for steam and condensate lines. As an alkanolamine, it maintains a constant alkalinity in boiler water and condensate, and it does not contribute solids to the boiler system. DEEA is utilized in the water treatment, gas treating, water-based and solvent-based coatings, and pharmaceutical industries, among others.

2-Diethylaminoethanol, also known as diethylethanolamine or -diethylamino, belongs to the class of organic compounds known as 1,2-aminoalcohols. These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. 2-Diethylaminoethanol is a very strong basic compound (based on its pKa). Diethylethanolamine is an irritant to the eyes, skin, and respiratory system. The Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health have set occupational exposure limits for workers handling the chemical at 10 ppm (50 mg/m3) over an eight-hour workday. Diethylethanolamine (DEAE) is a chemical compound with the molecular formula C6H15NO. DEAE can also be conveniently obtained from renewable sources. It is chemically stable and able to absorb carbon dioxide (CO2) from its surroundings. Diethylethanolamine is used as a corrosion inhibitor in steam and condensate lines by neutralizing carbonic acid and scavenging oxygen. In solution, it can decrease the surface tension of water when the temperature is increased. It is used as a precursor in the production of a variety of chemical commodities such as the local anesthetic procaine. It can be reacted with 4-aminobenzoic acid to make procaine.

Diethylethanolamine (DEEA), an industrial anticorrosive additive, was evaluated in rats for its potential toxicity. A 2-week inhalation exposure to 10 ppm revealed no signs of toxicity. At 56 ppm, rats exhibited signs of nasal irritation and corneal opacities. Significant mortality (males, 90% females, 50%) occurred at 301 ppm. Histopathology revealed inflammatory cell infiltrations of the nasal turbinate mucosa and squamous metaplasia after exposure to 56 ppm. In the 14-week subchronic study, rats were exposed to 0, 11, 25, or 76 ppm. During exposure to DEEA, transient signs of mild to moderate respiratory irritation (noises or rales) were observed with a frequency and severity that was dose dependent. These signs usually cleared within 1 hr post-exposure. However, at 76 ppm some rats continued to exhibit these respiratory signs overnight. There were no significant DEEA-induced changes in either blood chemistry or neurobehavioral parameters. Nasal cavities of rats exposed to 25 or 76 ppm revealed evidence of inflammatory cell infiltration, focal hyperplasia, and squamous metaplasia in the respiratory epithelium of the anterior nasal turbinates. Hypertrophic goblet cells, focal necrosis, and exudate in the nasal lumen were also seen at 76 ppm. DEEA vapors failed to produce persistent ocular or respiratory tract toxicity below 26 ppm. The no-observed-effect-level in this study was 10 ppm.

Alkyl alkanolamines are used in a variety of coatings, both water- and solvent-based. Their main function is to increase the solubility of other components and enhance solution stability. 

Alkyl alkanolamines such as N,N-dimethylethanolamine and, N,N-diethylethanolamine are particularly useful in waterborne coatings. They increase resin solubility or reducibility, aid pigment dispersion, and improve solution stability by reducing pH drift. This latter problem is often seen in architectural paints utilizing a volatile pH modifier such as ammonia. Studies have also shown that they provide an attractive alternative to 2-amino-2-methyl propanol (AMP). N,N-dimethylethanolamine and N,N-diethylethanolamine are both recommended for use in waterborne baking enamels and primer formulations where adhesion to a variety of topcoats is needed.
N,N-dimethylethanolamine is particularly suitable for white or pastel baking enamels because of its resistance to discoloration (“yellowing”). Tests have shown that, when N,N-dimethylethanolamine is used in baked waterborne coatings formulations, it offers superior scratch- and rub-resistance, as well as allowing an energy reduction of more than 20% in the bake cycle, compared to other commonly used alkanolamines, such as AMP. An additional advantage over AMP is that, as a tertiary amine, N,N-dimethylethanolamine does not tend to form water-soluble amides that remain in the film. 

Waterborne epoxy can-coating processes utilize alkyl alkanolamines, primarily N,N-dimethylethanolamine, to stabilize the final resin/solvent system and thus facilitate application by spraying, rolling, etc. Alkyl alkanolamines are also used in a number of cathodic electrodeposition systems. N-methylethanolamine, being a secondary amine, is often used to chain-extend high MW polyepoxides with a polyol. This is made water dispersible by neutralization to provide cationic groups in the polymer. A tertiary amine, such as N,N-dimethylethanolamine, is sometimes added as a catalyst, although N-methylethanolamine can form an “in-situ” tertiary amine catalyst by reaction with the polyepoxide. 

Alkyl alkanolamines react readily with long-chain fatty acids to form surface-active soaps. The products are waxy, noncrystalline materials which have widespread commercial importance as emulsifying additives in textile lubricants, polishes, detergents, pesticides and personal care products such as hand lotions, shaving creams, and shampoos.

Household Specialties and Personal Care:

The most common tertiary amine-based soaps are oleates and stearates. The oleate soap is water soluble; the stearate soap is not. Solutions of the oleate soap have very good detergent properties, are widely used with organic solvents, and are, typically, utilized in dry cleaning solvents. Alkyl alkanolamine stearate soaps are frequently used in hand lotions, cosmetic creams, cleansing creams, shaving creams, and shampoos. 

Fatty-acid soaps of N,N-diethylethanolamine and N,N-dimethylethanolamine are employed as emulsifying and dispersing agents for water-resistant waxes and polishes. These polishes may be used on metal, leather, glass, wood, ceramic ware, automobiles, floors, and furniture. The floor polishes are designed particularly for light-colored flooring. 

Textiles:

Surface-active alkyl alkanolamine soaps made primarily from oleic acid are used in cleaning and scouring textiles. When combined with chlorinated solvents, these soaps become wetting agents. Soluble in water and in most hydrocarbon solvents, they lather well in hard water. Combined with natural oils, such as linseed, olive, and castor oil, these soaps are utilized as textile lubricants, characterized by their excellent emulsifiability and ease of removal. Alkyl alkanolamine-based knitting oils prevent gum from clogging needles, and decrease the buildup of electric charge on the fiber during processing. The surface-active derivatives of alkyl alkanolamines also find use in desizing. 

Esters of N,N-dimethylethanolamine are used extensively in the textile industry as emulsifying agents. N-methylethanolamine is used as a brightening agent in the dyeing of polyester/cotton blends. 

Lubricants:

The addition of alkyl alkanolamine soaps to mineral oils produces a soluble oil used in greases, cutting and lubricating oils, petroleum-water demulsifiers, and oil emulsifiers. N,N-dimethylethanolamine is utilized in making sulfurized oils for extremepressure lubricants. Alkyl alkanolamines are also used in additives that lower the pour point of lubricating oils.

Gas treating:

Elimination of undesirable hydrogen sulfide from natural gas and refinery off-gases is almost universally accomplished by a process involving contact of the gas stream with a solution, and subsequent stripping of the acid gas from the solution. The process is referred to as sweetening. N-methyldiethanolamine is used in gas treating as a scrubbing and extraction agent, and provides the capability of selectively absorbing H2S in the presence of CO2.

Pharmaceuticals:

Alkyl alkanolamines and their derivatives are widely used as intermediates for the production of active pharmaceutical ingredients. For example, N,N-dimethylethanolamine is an intermediate in the synthesis of procaine, a valuable local anesthetic and an intermediate in the preparation of procaine penicillin G, an important antibiotic. N,N-dimethylethanol-amine and N-methylethanolamine are used in the synthesis of antihistamines (e.g., diphenhydramine hydrochloride) for the symptomatic relief of allergies, such as hay fever as well as the common cold. N-methyldiethanolamine is an intermediate in the production of analgesics that have sedative and antispasmodic effects. N,N-dimethylethanolamine is employed in the synthesis of Tamoxifen, used in the treatment of malignant diseases.

Water Treatment:

Alkyl alkanolamines are widely used in the water treatment industry. They are employed in the production of a number of important water treatment products, such as synthetic water-soluble polymeric flocculants and ion exchange resins. They are also used directly as corrosion inhibitors.

Flocculants: 
Acrylic and methacrylic acid esters of alkyl alkanolamines, particularly N,N-diethylethanolamine, are quaternized, typically, with methyl chloride or dimethyl sulfate and then copolymerized with acrylamide to give cationic polymeric flocculants. When added in trace quantities to water, they adsorb solid and colloidal particles by electrostatic attraction to form large “flocs,” which can then be readily separated.

They vastly improve solid/liquid separation processes such as sedimentation, filtration and flotation, and are thus widely used in the potable water and wastewater treatment industries to remove colloidal and suspended solids, as well as in the paper and mineral processing industries. They are also used in secondary sludge dewatering where, in conjunction with belt filter presses, high cake solid concentrations are obtained.

To avoid crosslinking in the copolymerization step, and subsequent loss in product performance, high quality raw materials are essential. 

Corrosion Inhibitors:

Alkyl alkanolamines are widely used as corrosion inhibitors in return-condensate steam and boiler systems. Two alkyl alkanolamines in particular, DMEA and DEEA meet the exacting requirements of this application. They have the correct combination of volatility and basicity to maintain a constant alkalinity in the boiling solution, vapor, and condensate. They do not form solid hydrates or react to form solid products which would impede line flow. These alkyl alkanolamines offer distinct advantages over morpholine and cyclohexylamine, the two volatile amines traditionally employed in this application. The lower molecular weight of DMEA enables a more efficient use, on a pound-for-pound basis, than cyclohexylamine, and gives significant cost benefits. Similarly, the superior ability of DMEA to neutralize CO2 results in a lower requirement to achieve a given pH, in the range 7.0 to 8.5, than any other standard amine. DEEA and DMEA provide better protection than cyclohexylamine in high-temperature condensates, and better protection than morpholine in long runs of low-pressure steam lines.
