Abstract
A carbonylation process is provided for conversion of olefinically unsaturated hydrocarbons to a mixture of esters or acids with a high ratio of iso:normal ester or acid by reaction with carbon monoxide and a hydroxylic compound, said process being carried out in the absence of added hydrogen or oxygen and in the presence of a palladium salt complexed with an arsine or stibine ligand as catalyst; 2-10 additional moles of arsine or stibine ligand per mole of catalyst may be present in said process to further enhance the ratio of iso:normal product and to promote catalyst stability. The catalyst, for example, may be palladium dichloride bis(triphenylarsine) or palladium dichloride bis(tri-p-tolyl arsine).
