Abstract
Vinyl acetate is prepared by reacting acetic acid with ethylene and molecular oxygen in the gaseous phase in the presence as a catalyst of elementary palladium, platinum, ruthenium, rhodium or iridium together with a manganese compound. The catalyst is supported on a carrier which may be active carbon, pumice, silica gel or aluminium oxide and palladium is the preferred metal. Manganese acetate, sulphate or chloride may be used, for instance by impregnating the carrier with a 1-10% solution.ALSO:A catalyst for the preparation of vinyl acetate comprising elementary palladium, platinum, ruthenium, rhodium or iridium, and a manganese compound in a carrier is prepared in an example by impregnating granulated active carbon with palladium chloride in 50% hydrochloric acid, adding a mixture of hydrazine hydrate and sodium hydroxide washing and drying and finally impregnating with a 10% solution of manganese acetate and drying.
