Dimethyl Adipate (DMA) is the methyl ester of adipic acid, a colorless and transparent liquid. People use DMA as a solvent for high-end coatings, inks and additives, also as a papermaking additive in the papermaking industry, as well as plasticizer in the fiber resin field. In addition, factories also use it as raw material to prepare pesticides and pharmaceutical intermediates. Most manufacturers use adipic acid and methanol in the presence of a catalyst to produce it. Offered here at Integratechem, one of the leading and professional China manufacturers and suppliers.

How to synthesize Dimethyl Adipate?
Firstly, adipic acid reacts with methanol for esterification under the action of a catalyst.
Secondly, distillation separation allows the esterification reaction to proceed continuously;
Thirdly, neutralization and water washing to reduce the acid value;
In addition, some manufacturers separate dimethyl adipate from dibasic ester.

FAQ
What is Dimethyl Adipate?
What is Dimethyl Adipate?
Dimethyl Adipate (DMA) is an ester of adipic acid, also known as DBE-6 dibasic ester and adipic acid dimethyl ester. People widely use DMA in the pesticides and pharmaceutical intermediates field and chemical industries such as paints, and coatings.
How are esters classified?
How are esters classified?
According to the chemical structure. People divided them into: (1) Phthalate esters; (2) Aliphatic dibasic acid esters; (3) Phosphate esters (4) Epoxy compounds; (5) Polymeric plasticizers; ( 6) Benzene polyester; (7) Chlorine-containing plasticizer; (8) Alkyl sulfonate ester; (9) Polyol ester; (10) Other plasticizers.
Do ester compounds need to be neutralized and washed with water to remove the catalyst after esterification?
Is it necessary to neutralize and wash with water to remove the catalyst?
If manufacturers use a catalyst that has good catalytic activity and can remove it from the system, then it doesn’t need neutralization and water washing, or a catalyst that forms a homogeneous phase with the ester at the reaction temperature and precipitates in a solid state after lowering the temperature.
What is esterification?
What is esterification?
Indeed, the carboxylic acid reacts with alcohol in the presence of a small number of catalysts (concentrated sulfuric acid, dry hydrogen chloride, strong acid type ion exchange resin) to form esters. Therefore, manufacturers call this reaction esterification. In short, esterification is a reversible reaction, and when equilibrium generated, a certain number of reactants and products are present.
What are the functional groups of dimethyl adipate ?
What are the functional groups of dimethyl adipate ?
The functional group of citrate esters is also -COO-. Dehydration of carboxyl group (-COOH) and hydroxyl group (-OH) form it in deed.
What are the applications of dimethyl adipate ?
What are the applications of dimethyl adipate ?
People use dimethyl adipate in the manufacture of pesticides and pharmaceutical intermediates. Also used as a solvent for high-end coatings, inks and additives. In addition, as a papermaking additive in the papermaking industry as well as plasticizer in the fiber resin field.
How to calculate the original consumption ratio of dimethyl adipate ?
How to calculate the original consumption ratio of dimethyl adipate ?
Suppliers in China calculate as follows: Since adipic acid is a dicarboxylic acid, if the alcohol involved in the reaction is a monol, then one molecule of adipic acid reacts with two molecules of a monol to produce a molecule of dimethyl adipate. So, if we multiply the coefficients corresponding to the chemical reaction in their respective molecular weights, therefore, the ratio between the three products is the ratio of raw material consumption.
What is the most commonly used cost-effective plasticizer ester?
Commonly used and cost-effective plasticizer
Indeed, manufacturers think that the most cost-effective plasticizers are dibutyl phthalate and dioctyl phthalate.
What esters can be used as mosquito repellents
What esters can be used as mosquito repellents
The ester offered from suppliers in China is Dimethyl phthalate
How are esters chemically named?
How are esters chemically named?
In short, the word “ester” can be preceded by the corresponding carboxylic acid and alcohol names. The word “alcohol” can generally be omitted, that is, “some” acid “some” ester. But the ester of polyols, generally put the “acid behind, called” an alcohol an acid ester.”
How to increase the yield of ester?
How to increase the yield of ester?
In factories, heating and adding catalyst can only accelerate the reaction speed, but has no effect on the composition of the balanced material. In order to increase the yield of esters, manufactuers and suppliers in China often added excessive carboxylic acids and alcohols, or they constantly removed the resulting water from the reaction mixture. If the boiling point of the ester produced is very low, as a result, factories can steam ester out. In short, the equilibrium has changed to improve the yield of ester. For example, the industrial production of ethyl acetate in factories use excessive acetic acid, factories steamed the generated ethyl acetate and water azeotrope (water 8.6%, ethyl acetate 91.4%, constant boiling point 70.45℃) out. So that the balance has changed, and then factories continue to add acetic acid and ethanol, continue to steam ethyl acetate and water, continuous production.
What is saponification?
What is saponification?
People call the hydrolysis of esters in alkali solution as saponification reaction, which is because the advanced fatty acid salt obtained by alkaline hydrolysis of grease is the reason of soap.
