Dimethyl adipate is the organic compound with the formula (CH2CH2CO2CH3)2. It is a colorless oily liquid. Although the main commercial interest in adipates is related to the production of nylons, this diester is used as a plasticizer, a solvent for paint stripping and resins, and a pigment dispersant.[2]
Preparation
Dimethyl adipate is prepared by esterification of adipic acid with methanol. Less conventional routes include the hydroesterification of butadiene and the carbonylation of 1,4-dimethoxy-2-butene.[2]
It reacts with concentrated ammonia to give the diamide (CH2CH2C(O)NH2)2.
Toxicity
Esters of adipic acid exhibit low acute toxicities in animal models. The -1">50 of this dimethyl ester is estimated at 1800 mg/kg (rat, i.p.).[2]
Uses
Dimethyl adipic acid is used in cosmetics as an emollients and for skin conditioning. It is also used in agrochemicals and dyes, as well as a precursor for the production of pharmaceutical active ingredients and as a component of dibasic esters.[3][4]
