Abstract
A direct hydrocarbonylation process for the production of 1,4-butanediol is described. The process comprises reacting allyl alcohol with carbon monoxide and hydrogen in an alcohol solvent in the presence of a catalyst system comprising a rhodium complex, a trialkyl phosphine, and a diphosphine. The process gives a high yield of 1,4-butanediol in a one-step reaction.
