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 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.
