Process for the preparation of methyl acrylate from methyl acetate

Abstract

The present application provides a method for preparing methyl acrylate from methyl acetate, comprising reacting methyl acetate with an aldehyde source in the presence of a solid base catalyst to obtain the methyl acrylate, the solid base catalyst comprising the following components in mass fraction: a) a catalytic amount of alkali metal oxide; and b) 50-80 parts of a carrier; wherein the carrier is silica with a silicon hydroxyl density of 0.6-1.5 Si-OH / nm 2 The present application also provides a solid base catalyst, its use and a preparation method. The present application obtains a methyl acrylate synthesis route with improved yield, selectivity, and long-term catalytic activity, which can be industrialized and solves the problem of a large excess of methyl acetate production capacity.
