Abstract:
The invention relates to a process for transvinylation of a carboxylic acid feedstock with a vinyl ester feedstock to obtain a vinyl ester product and the corresponding acid of the vinyl ester feedstock in the presence of one or more ruthenium catalysts, wherein a) the vinyl ester feedstock, the carboxylic acid feedstock and a ruthenium catalyst are fed to the reactor, and b) the transvinylation reaction is carried out, characterized in that a carbonyl-free Ru(III) carboxylate is used as the ruthenium catalyst and in that no carbon monoxide is supplied, c) the reaction is carried out at a temperature of 110 to 170° C., d) upon completion of the transvinylation reaction, the vinyl ester feedstock and the corresponding acid are separated from the reaction mixture by distillation, e) the vinyl ester product is separated by distillation from the bottom product of the distillation, and f) the remaining reaction mixture is recycled into the reactor.
