Abstract
Pentenoic acids are selectively prepared via hydroxycarbonylation of butadiene with carbon monoxide and water, at a temperature above 30.degree. C., under a partial pressure of carbon monoxide, measured at 25.degree. C., equal to or greater than 0.5 bar, in the presence of a catalytically effective amount of an iridium-based catalyst and an iodine-containing or bromine-containing promoter therefor, in a solvent medium, wherein the iodine or bromine/iridium molar ratio is less than or equal to 20/1 and the concentration by weight of water in the reaction mixture is less than or equal to 8%.
