Abstract

Esters are obtained by treating an olefine of the formula R1(R2)C: CHR3, in which R1, R2 and R3 are hydrogen atoms or alkyl radicals, with a carboxylic acid and a gas containing molecular oxygen in the vapour phase in the presence of a catalyst containing a metal of the platinum group. The catalyst may contain the metal in elementary form or in the form of a salt and may also contain promoters, e.g. sodium vanadate or molybdate, cobalt or copper acetate, vanadium pentoxide or phosphoric acid. The catalyst is preferably supported, e.g. on active carbon, charcoal, pumice or silica gel. The reaction may also be promoted by including a small proportion of steam and (or) hydrogen chloride in the reaction mixture. The reaction may be effected at 50-250 DEG C. and at atmospheric, reduced or raised pressure. In a typical example, a mixture of ethylene and oxygen is passed through acetic acid at 55 DEG C., to saturate the gas with acetic acid vapour, and the mixture is then passed at 150 DEG C. over palladium supported on active carbon vinyl acetate and ethylidene diacetate are obtained. Propylene is also mentioned as a suitable olefine.
