Abstract
Abstract A carbonylation process is provided for conversion of olefinically unsaturated hydrocarbons to a mixture of esters or acids with an increased ratio of normal:iso (i.e., straight: branched) ester or acid by reaction with carbon monoxide and a hydroxylic compound, said process being carried out in the presence of a palladium salt complexed with a phosphine ligand as a catalyst and tin cocatalysts or promoters. For example, the catalyst may be palladium dichloride bis(triphenylphosphine) and the tin cocatalyst or promoter present may be stannous chloride dihydrate.
