Abstract

PURPOSE: To separate methyl acetate, and methanol from an azeotropic mixture thereof, easily and economically in an industrial scale, by distilling the mixture in the presence of a C2-5 diol.
CONSTITUTION: A mixture of methyl acetate and methanol is distilled in the presence of a C2-5 diol, e.g. ethleneglycol, butane diol etc., to separate methyl acetate substantially free from methyl acetate, The method is useful for the separation of methyl acetate and methanol from their mixture by-produced in the ester exchange of, e.g. esp. 1,4-diacetoxybutane or 1,4-diacetoxybutene-2 with methanol using butane diol which is formed by the ester exchange.
