Original Abstract Submitted

A process produces a target alcohol by hydrogenation of an ester formed by alkoxycarbonylation of diisobutene. The diisobutene stream used in the alkoxycarbonylation is subjected to a distillation prior to the alkoxycarbonylation in order to enrich -trimethylpent--ene in the stream to be alkoxycarbonylated. The alkoxycarbonylation is carried out with an alcohol and carbon monoxide in the presence of a homogeneous catalyst system that comprises at least one metal from group to of the periodic table of the elements or a compound thereof, a phosphorus-containing ligand and an acid.
