Mixed Dibasic Acid Esters are esters of dicarboxylic acids. Dicarboxylic acids react with various alcohols to form related dicarboxylic acid esters. They are mixtures of various dicarboxylates. Common mixed dibasic acid esters are【Dibasic Ester】CAS No 95481-62-2 and 【Diisobutyl DBE】. These esters including dibasic ester are environmentally friendly high boiling point solvents. People use them in automotive coatings, colored steel plate coatings. In addition, we also use mixed dibasic acid esters in can coatings, enameled wires and home appliance materials, furniture and wood coatings.

Dibaisc ester (DBE) is a methyl ester of a mixed dicarboxylic acid，a colorless and transparent liquid. 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. Most importantly, dibaisc ester (DBE)
Dibasic ester (DBE) is an environmentally friendly solvent with the characteristics of good solubility, low volatility, easy flow, high safety, non-toxic, and good photochemical stability. With a boiling range of 195-230°C, it is widely used in the paint, coating, ink industry and organic synthesis intermediates. 1. Product Description 2. Specification
Diisobutyl DBE (DBE-IB) is a mixed diisobutyl ester of succinic acid, glutaric acid and adipic acid. It has the characteristics of low odor, low vapor pressure, biodegradability, excellent thermal and hydrolytic stability. DBE-IB is used as a coalescing aid in waterborne coatings, as a solvent in solvent coatings and printing
Mixed Dibasic Acid Esters mainly include Dibasic Ester and Diisobutyl Dibasic Ester.
It is biodegradable and environmentally friendly high boiling point solvent.
In addition, people also use them in can coatings, enameled wires and home appliance materials, furniture and wood coatings and other industries.
We also can convert mixed dibasic acid esters into useful plasticizers products.
Weifang Integratechem Co., Ltd. is a leading, experienced and professional supplier of mixed dibasic acid esters. Now we manufacture and supply a series of mixed dibasic acid esters, mainly used as plasticizers, solvents, adhesives, coatings, inks, organic Synthetic intermediates, etc. We are continuously committed to providing customers with competitive prices and consistent service to meet their needs.
According to the chemical structure. Can be divided 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.
The mixed dibasic acid and the corresponding alcohol undergo esterification reaction, distillation and purification to generate mixed dibasic acid esters, and then undergo transesterification reaction to generate other mixed dibasic acid esters.
Use a catalyst that has good catalytic activity and can be removed from the system without 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.
The carboxylic acid and alcohol can be heated in the presence of a small number of catalysts (concentrated sulfuric acid, dry hydrogen chloride, strong acid type ion exchange resin) to form esters. This reaction is called esterification. Esterification is a reversible reaction, and when equilibrium is reached, a certain number of reactants and products are present.
The functional group of mixed dibasic acid esters is -COO-, which is formed by dehydration of carboxyl group (-COOH) and hydroxyl group (-OH). Mixed dibasic acid esters have the characteristics of typical ester functional groups, including saponification and hydrolysis reactions. Transesterification reactions are mainly used to convert ester products into useful plasticizers and other polyester products.
As a biodegradable and environmentally friendly high boiling point solvent, widely used in automotive coatings, colored steel plate coatings, can coatings, enameled wires and home appliance materials, furniture and wood coatings and other industries.
Since mixed dibasic acid esters are dicarboxylic acid, if the alcohol involved in the reaction is a monol, then one molecule of mixed dibasic acid esters reacts with two molecules of a monol to produce a molecule of mixed dibasic acid esters. After the coefficients corresponding to the chemical reaction are multiplied by their respective molecular weights, the ratio between the three products is the ratio of raw material consumption.
The most cost-effective plasticizers are dibutyl phthalate and dioctyl phthalate.
Dimethyl phthalate
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.”
Heating and adding catalyst can only accelerate the reaction speed, and has no effect on the composition of the balanced material. In order to increase the yield of esters, excessive carboxylic acids and alcohols are often added, or the resulting water is constantly removed from the reaction mixture. If the boiling point of the ester produced is very low, the ester can also be steamed out. In short, the equilibrium is destroyed to improve the yield of ester. For example, the industrial production of ethyl acetate is to use excessive acetic acid, the generated ethyl acetate and water azeotrope (water 8.6%, ethyl acetate 91.4%, constant boiling point 70.45℃) to steam out, so that the balance is destroyed, and then continue to add acetic acid and ethanol, continue to steam ethyl acetate and water, continuous production.
The hydrolysis of esters in alkali solution is also called saponification reaction, which is because the advanced fatty acid salt obtained by alkaline hydrolysis of grease is the reason of soap.
