PROCESS FOR THE CARBONYLATION OF ETHYLENICALLY UNSATURATED COMPOUDS

摘要

A process for the carbonylation of ethylenically unsaturated compounds is described. The process comprises reacting an ethylenically unsaturated compound with carbon monoxide in the presence of a source of hydroxyl groups and a catalyst system. The catalyst system is obtained by combining: (a) metal of Group VIII or a compound thereof: and (b) a bidentate phosphine of general formula (I) The carbonylation reaction is carried out at a temperature of between -30°C to 49°C and under a CO partial pressure of less than 30 x10<5> N.m<-2>.
