Abstract
Carbonylation of olefins is carried out in the presence of a hydroxylic compound, carbon monoxide and a catalyst system comprising an organic phosphine liganded palladium compound and a perfluorosulfonic acid.
Claims14
In an improved catalytic carbonylation process for preparing acids and esters by reacting an olefinically unsaturated compound, carbon monoxide and a hydroxylic compound, at about 50.degree. to about 150.degree. C., in the presence of a catalyst comprising an organic phosphine liganded palladium compound and an acid, wherein the improvement comprises using a perfluorosulfonic acid as the acid.
