Title: Process for the preparation of vinylesters

Abstract: A process for the catalytic conversion of carboxylic acids with acetylene to vinylesters. At least one, preferably saturated, secondary carboxylic ester and/or at least one, preferably tertiary carboxylic acid is (are) passed in the gas phase together with acetylene at an elevated temperature, preferably in the range of from 150 to 400.degree. C., over a catalyst comprising zinc and a solid inert oxidic carrier, preferably alumina. The carboxylic acids have advantageously the following formula: ##STR1## in which R.sub.1 is H or an alkyl group and R.sub.2 and R.sub.3 are alkyl groups, the total number of C-atoms of R.sub.1 +R.sub.2 +R.sub.3 being in the range of from 3 to 18. These vinylesters have a good stability and are particularly useful components in emulsion paints and as modifiers in alkyd and epoxy resin.
