How to produce Dimethyl Glutarate?
Firstly, glutaric acid reacts with methyl alcohol 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, manufacturer separates dimethyl glutarate from dibasic ester.

FAQ
What is Dimethyl Glutarate?
What is Dimethyl Glutarate?
Glutarate (DMG) is an ester of glutaric acid, also known as DBE-5 dibasic ester and glutaric acid dimethyl ester. People buy dimethyl glutarate and widely use it in the pharmaceutical field and chemical industries such as plastics, paints, and coatings.
How are esters classified?
How are esters classified?
According to the chemical structure, suppliers China 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 glutarate ?
What are the functional groups of dimethyl glutarate ?
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 glutarate ?
What are the applications of dimethyl glutarate ?
People buy dimethyl glutarate and use it in the production of agricultural chemicals and water treatment chemicals. Also used as an material in the production of cleaning agents, lubricants, coating agents, rolling oils, metal working fluids, foaming agents and functional fluids.
How to calculate the original consumption ratio of dimethyl glutarate ?
How to calculate the original consumption ratio of dimethyl glutarate ?
Suppliers in China calculate as follows: Since glutaric acid is a dicarboxylic acid, if the alcohol involved in the reaction is a monol, then one molecule of gluartic acid reacts with two molecules of a monol to produce a molecule of dimethyl glutarate. 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.
