Dibaisc ester (DBE) is a colorless and transparent liquid, a methyl ester of a mixed dicarboxylic acid. With a boiling range of 195-230 °C, DBE is a high boiling point solvent. With the characteristics of good solubility, low volatility, non-toxic, also it is an environmentally friendly solvent. Manufacturers or suppliers in China mainly use it in the coating industry. In addition, dibaisc ester (DBE) is widely used in the paint, ink industry and organic synthesis intermediates. Furthermore, dibasic ester factories make DBE from dibasic acid and methanol.

How to synthesize dibasic ester?
Firstly, manufacturers make dibasi 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.

What is dibasic ester ?
What is dibasic ester ?
Dibaisc ester (DBE) is a methyl ester of a mixed dicarboxylic acid，a colorless and transparent liquid. DBE is a high boiling point solvent. Also it is an environmentally friendly solvent. Most importantly, dibaisc ester (DBE) is widely used in the paint, coating, ink industry and organic synthesis intermediates.
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.
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 dibasic ester ?
What are the functional groups of dibasic ester ?
The functional group of citrate esters is also -COO-. Dehydration of carboxyl group (-COOH) and hydroxyl group (-OH) form it in deed.
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.
