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][3]
Preparation
[edit | edit source]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
[edit | edit source]Esters of adipic acid exhibit low acute toxicities in animal models. The LD50 of this dimethyl ester is estimated at 1800 mg/kg (rat, i.p.).[2]
