摘要： A process for the catalytic conversion of carboxylic acids with acetylene to vinylesters. At least one, preferably saturated, secondary carboxylic acid 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°C, over a catalyst comprising zinc and a solid inert oxidic carrier, preferably alumina. The carboxylic acids have advantageously formula (I) in which R1 is H or an alkyl group and R2 and R3 are alkyl groups, the total number of C-atoms of R1 + R2 + R3 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 resins.
