摘要： Butadiene or derivative thereof is selectively hydroxycarbonylated into at least one pentenoic acid (the pentenoic acids are themselves facilely converted, via hydroxycarbonylation, into adipic acid, a basic starting material for the production of nylon 66 polymers), by reacting same with carbon monoxide and water, at a pressure greater than atmospheric, in the presence of a catalytically effective amount of (1) a palladium catalyst which is soluble in the medium of reaction and (2) crotyl chloride, the amount of the crotyl chloride being at least two mol thereof per mole of palladium values and said palladium values/crotyl chloride at least in part comprising a palladium/crotyl pi-complex, and the amount of water present in the medium of reaction being no greater than about 20% by weight thereof.
