ABSTRACT:
A process for the carbonylation of butadiene or a butadiene derivative in the presence of (i) carbon monoxide, (ii) an alcohol or water, and (iii) a catalyst system comprising palladium, a carboxylic acid and a monodentate phosphine ligand. The amounts of reactants during the carbonylation process are controlled so that the molar ratio of butadiene or butadiene derivative to palladium in the reaction mixture is less than about 70:1, the molar ratio of carboxylic acid to palladium is greater than about 10:1 and the molar ratio of alcohol or water to butadiene or butadiene derivative is less than about 2:1.2. Good selectivity and conversions are advantageously achieved.
