Abstract
PURPOSE: To obtain an ethylidene acetate and methyl acetate useful as raw materials for a variety of industrial chemicals, rationally, by the reaction of dimethyl acetal or 1-methoxy-1-acetoxyethane, with acetic anhydride, optionally in the presence of a catalyst.
CONSTITUTION: Dimethylacetal (chemical name: 1,1-dimethoxyethane) or 1-methoxy-1-acetoxyethane is reacted with acetic an hydride, if necessary in the presence of a catalyst, preferably an acid catalyst, at a temperature of preferably 0W250°C, to give an ethylidene acetate [mainly ethylidene diacetate (chemical name; 1,1- diacetoxyethane)] and methyl acetate. Dimethyl acetal which has been a by-product, is utilized effectively, to produce the ethylidene diacetate useful as a precursor for vinyl acetate.
