说明

一般描述

Its IR spectra in the vapor phase and in solution form (in CS2 and CCl4) have been reported.[1] It can be synthesized from dimethyl ether via carbonylation in the presence of halide-free catalysts based on zeolites.[2] It has also been reported to be formed during the synthesis of poly(vinyl) alcohol (PVA). It undergoes transesterification reaction with n-octanol in the presence of Amberlyst 15 catalyst to afford octyl acetate and methanol.[3]
Methyl acetate 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.[4]
 

应用

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.[5]
Methyl acetate may be used in the following:
  • As acyl acceptor in the preparation of biodiesel.[6]
  • Synthesis of ethanol.[7]
  • Preparation of n-butyl acetate, via transesterification reaction with n-butanol in the presence of acidic catalysts.[3]
It may also be used as a precursor in the synthesis of the following:[8]
  • acetic anhydride
  • methyl acrylate
  • vinyl acetate
  • ethyl amide
