DIBASIC ESTER

Dibasic ester or DBE is an ester of a dicarboxylic acid. Depending on the application, the alcohol may be methanol or higher molecular weight monoalcohols.

Dibasic Ester (DBE) and its fractions serve as raw materials for plasticizers, polymers.

Dibasic ester (DBE) and its fractions serve as raw materials for plasticizers, polymers. wet strength paper resins and other specialty chemicals. These applications are growing rapidly as new uses are found for DBEs as building blocks.

Applications:

Plasticizers- Certain esters of adipic, glutaric, and succinic acids (as mixtures or individually) are excellent plasticizers for various polymer systems including polyvinyl chloride resins.

Polymer Intermediate- As a source of adipic, glutaric and succinic acids and their mixtures, Diabasic Esters provide unique polymer structures. By the selection of the proper DBE fraction, properties, such as low temperature flexibility, can be tailored to meet specific needs.

Polyester Polyols for Urethanes- Polyols based on DBE are used to make polyurethane elastomers, coatings and both flexible and rigid foams.

Wet-Strength Paper Resins- DBE-2, DBE-5, and DBE-9 are particularly useful in the preparation of long-chain water soluble polyamides of the type which can be reacted with epichlorohydrin to form wet-strength paper resins.

Polyester Resins- DBEs are used extensively in the manufacture of saturated and unsaturated polyester resins.

Specialty Chemical Intermediate- Dimethyl succinate (DBE-4), dimethyl glutarate (DBE-5) and dimethyl adipate (DBE-6) are abundant and economical sources of the adipic, glutarate and succinic moieties for organic synthesis.

Mixtures of different methyl dibasic esters are commercially produced from short-chain acids such as adipic acid, glutaric acid, and succinic acid. They are non-flammable, readily biodegradable, non-corrosive, and have a mild, fruity odour.

Dibasic esters of phthalates, adipates, and azelates with C8 - C10 alcohols have found commercial use as lubricants, spin finishes, and additives.

Dibasic esters are used in paints, coil coatings, paint strippers, coatings, plasticisers, resins, binders, solvents, polyols, soil stabilization, chemical grouting, oilfield drilling fluids, crop protection products, cedar spray, and adhesives.

Dibasic ester is a solvent that is obtained from blending of dimethyl glutarate, dimethyl succinate and dimethyl adipate and that is a strong solvent for polyester resins. Blending ratio of three esters differs according to the producer. Typical composition and some properties of a widely used product of Invista, named DBE, are given below:

Typical chemical composition:

59% Dimethyl glutarate
20% Dimethyl succinate
21% Dimethyl adipate

Boiling range: 196-225°C
Evaporation number relative to ether: >100
Specific gravity: 1,092
Refractive index: 1,423
Flash point: 103°C

Dibasic esters are excellent solvent substitutes in many parts cleaning and stripping applications.

Commercial acceptance and use of dimethyl esters and dibasic esters continues to increase due to their positive economic, environmental and performance characteristics.

Dimethyl esters and dibasic esters can be used alone or in customized ester and co-solvent blends to replace more conventional and increasingly regulated materials and industrial solvents, including, but not limited to:

N-methyl-2-pyrrolidone (NMP)
MEK
methylene chloride
isophorone
certain glycol ethers and their acetates
acetone
cresylic acid

Because of their low vapor pressure, dibasic esters will evaporate very slowly and can be recycled for repeated application.

The low vapor pressure also allows formulators and end-users to remain compliant with applicable VOC regulations.

For instance, certain DME blends under the Sta-Sol® ESS label qualify for LVP-VOC consumer product exemptions due to a vapor pressure of less than .1 mm Hg @ 20 °C.

A dibasic ester based formulation can be the perfect alternative for dissolving polar substances such as polyurethane, polyester, and acrylate resins, plus a wide range of coatings and inks.

Dibasic ester technology is used in a wide variety of applications, including:

Coil and Can Coatings
Polyester and Epoxy Sealing Coat
Automotive Coatings
Industrial Paint
Wire Enamel Coatings
Formulations
HI&I Cleaning
Liquid detergents
Pesticides and insecticides
Textile lubricants
Corrosion inhibitors
Printing inks
Foundry Core Resin Binder
Soil Stabilization
Wet Strength Paper Resins

Depending on the application, the combination of dimethyl glutarate, dimethyl adipate and dimethyl succinate can be custom tailored as a slowly evaporating cleaning and stripping solvent.

A dibasic ester based solvent blend may be considered a “greener” or environmentally preferable and safer product due to several safety and regulatory attributes, including: 

-Environmental:

Low VOC (may qualify for LVP-VOC consumer product exemptions)
Readily Biodegradable
Not included CERCLA/SARA hazardous substances list
Not considered a hazardous waste under RCRA (waste status may change depending on spent resins and substances included in waste stream)

Low levels of toxicity
Low Odor
Main components not subject to Proposition 65
Included on EPA list of safer chemicals for use in Safer Choice formulations

-Safety:

Non Flammable
Non Corrosive
Non Hazardous DOT
High Flash Point
High Boiling Point
Slowly Evaporating Solvents

Dibasic esters are generally defined as dialkyl esters of dicarboxylic acids capable of undergoing reactions at the ester group, including both hydrolysis and saponification. The acid portion of the dibasic ester may be derived from such dibasic acids as oxalic, malonic, pimelic, suberic and azelaic acids, as well as mixtures thereof.

Examples of suitable dibasic esters for use in the present invention include, but are not limited to, dimethyladipate, dimethyl glutarate, dimethyl succinate, and mixtures thereof.

A particularly preferred dibasic ester is a mixture of dimethyl adipate, dimethyl glutarate, and dimethyl succinate in varying weight ratios.

The surfactant component aids in both emulsifying the dibasic ester plus antioxidant emulsion and facilitates the enhanced uptake of the composition onto the surface of the synthetic textile substrate. Suitable surfactants which may be employed include, but are not limited to, nonionics, anionics, cationics, amphoterics and zwitterionics.

Dibasic Esters (DBE), also known as DMEs (dimethyl esters), are chemical compounds composed of a mixture of three dibasic esters namely: dimethyl adipate (DMA), dimethyl glutarate(DMG) and dimethyl succinate (DMS). DBE is used in a variety of solvent applications both as a standalone solvent and in formulations; however, it can be used as a chemical intermediate. It has been considered as green solvent to replace toxic and highly volatile solvents such as methylene chloride. ,

There are six DBE blends based on different fractions of the pure esters for specialty applications (DBE2, DBE-3, DBE-4, DBE-5, DBE-6, DBE-9). The most popular DBE blends used in paint stripping formulas contain about 90 percent DMA. Also, DBEs have applications in coating industry to clean adhesives, polyurethane foams and unsaturated polyester resins.

Dibasic esters are generally produced by catalytic esterification of dicarboxylic acids. Adipic acid, glutaric acid and succinic acid react with methanol in presence of an acidic catalyst (homogeneous or heterogeneous) with the following two stage cascade reactions:

Diacid + Methanol <---------> Monomethyl Ester + water

Monomethyl Ester + Methanol <---------> Dimethyl Ester + water

Since it is an equilibrium reaction, removing water from the system causes the reaction to shift towards formation of the desired product according to Le Chatelier’s principle. By studying phase equilibrium, it is possible to find any potential azeotrope and figure out the best way to separate water from the system. Also, boiling range of the components is extremely important in design of process. 

DMA, DMG and DMS are the dimethyl esters of six, four and five carbon dicarboxylic acids respectively. They are very similar in structure differing by just one alkyl carbon. 

DBE blend is a clear, colorless liquid, with mild odor. It is an excellent alternative to other traditional solvents because of some of its properties such as; Low (negligible) toxicity, Low vapor pressure (high boiling point), slow evaporation, high flash point, high miscibility with most organic solvents, low miscibility with water, biodegradability. 

Dibasic esters are produced from esterification reaction of dicarboxylic acids of adipic, glutaric and succinic acids with methanol in presence of acidic homogeneous or heterogeneous catalysts. These valuable carboxylic acids are available in waste streams of adipic acid and caprolactam manufacturing plants which have been incinerated mostly in order to remove impurities. The idea for recovery of adipic acid along with glutaric and succinic acids from the waste streams into diesters have been investigated since 1960’s. The process waste streams were esterified in presence of methanol in continuous reaction, extraction and distillation columns which yielded high purity of diesters. The final product is a mixture of diesters which is separated from the solvent by distillation.

Use of extracting solvent introduces some disadvantages to the system such as the need for solvent recovery in the final product stream which makes the process less economical. Besides, as a result of esterification of a mixture of diacids (adipic, glutaric, succinic), there is a mixture of diesters (DMA, DMG, DMS) in the product stream which have different solubility values with a particular solvent.

The mixsture is a mild to severe skin irritant and a moderate eye irritant, but is not a skin sensitizer in animals.Toxic effects described in animals from exposure by inhalation include upper respiratory tract irritation. A single 4-four exposure to 60 ppm caused transient corneal opacity and transient increases in the distance from the cornea to the anterior surface of the lens of the eye. Toxity described in animals from repeated exposure by inhalation include decreased weight gain, absolute and relative liver weight decrease, and degeneration of olfactory epithelium(nasal tissue).

Toxicity described in animals from repeated exposure by ingestion include weight loss, but there were no pathological abnormalities noted.

A single application of 10 ul to the eye caused corneal opacity. The administration of 1o-100 ul of a similar mixture caused corneal opacity, transient increases in corneal thickness, and transient corneal anesthesia. A single application of approximately 60 mg/kg to the skin caused transient increases in the distance from the cornea to the anterior surface of the lens of the eye.

The mixture does not produce genetic damage in animals, or in bacterial cell cultures, but it was positive in one study with cultures, but it was positive in one study with cultured mammalian cells. Animal testing indicates that this mixture does not have developmental, or reproductive effects.
