Abstract

The paper presents the results of a study on the production of vinyl acetate in a heterogeneous-catalytic manner in the presence of catalysts of zinc acetate/γ -Al2O3, zinc acetate/activated carbon, PHA, PHA-6, in the temperature range of 140-260 ° C and the acetylene and acetic acid molar ratio 3: 1 and 1: 5 environment of the studied catalysts turned out to be the most efficient zinc acetate/γ - Al2O3, in the presence of which a high yield of vinyl acetate is observed, at a temperature of 220 ° C and a molar ratio of acetylene and acetic acid is 4.5-5.0:1
