General description

Methyl acetate (MA) is an aliphatic ester that can be prepared via carbonylation of dimethyl ether over zeolites. MA is formed as a by-product during the preparation of polyvinyl alcohol from acetic acid and methanol.

Application

Methyl acetate may be used for the preparation of fatty acid methyl esters and triacetin from rapeseed oil via non-catalytic trans-esterification reaction under super-critical conditions.

Other Notes

The article number 296996-6X1L will be discontinued. Please order the single bottle 296996-1L which is physically identical with the same exact specifications.
