CA 2759810
A process for the selective production of vinyl ester by the reaction of a carboxylic acid with acety-lene under heterogeneous catalytic conditions is disclosed and claimed. In a preferred embodiment of this invention, reaction of benzoic acid and acetylene in the presence of supported platinum catalyst at a temperature of from about 100 to 180°C results in quantitative yields of vinyl ben-zoate.
L'invention porte sur un procédé pour la production sélective d'un ester vinylique par la réaction d'un acide carboxylique avec de l'acétylène dans des conditions de catalyse hétérogène. Dans un mode de réalisation préféré de cette invention, la réaction d'acide benzoïque et d'acétylène en présence d'un catalyseur au platine supporté à une température d'environ 100 à 180°C conduit à des rendements quantitatifs de production de benzoate de vinyle.
