Abstract: Production of 1,6-hexanediol of purity at least 99 % comprises hydroformylating 3-, 4- or 2-pentenoic acid alkyl ester with carbon monoxide and hydrogen in presence of rhodium compounds and tertiary organic polyphosphites, hydrogenating in chromium-free mainly copper-containing catalysts; and purifying the resulting diol mixture by fractional distillation. Production of 1,6-hexanediol of purity at least 99 % comprises: (1) hydroformylating 3-, 4- or 2-pentenoic acid alkyl ester with carbon monoxide and hydrogen in presence of rhodium compounds and tertiary organic polyphosphites to a mixture mainly of 5-, 4- and 3-formylvaleric acid esters; (2) hydrogenating the ester mixture in chromium-free mainly copper-containing catalysts; and (3) purifying the resulting diol mixture by fractional distillation.

Abstract: Alkyl 6-hydroxycaproates (I) preparation comprises reacting alkyl 2-, 3- and/or 4-pentenoates (II) with carbon monoxide and hydrogen to form 3-, 4- and 5-formylvalerates (III); hydrogenating and separating (I) from alkyl 6C hydroxycarboxylates (IV) produced. First step is in presence of rhodium compound and tertiary organic polyphosphite (A) and the hydrogenation uses catalyst from subgroup I or VI-VIII. Preparation of alkyl 6-hydroxycaproates (I) comprises reacting alkyl 2-, 3- and/or 4-pentenoates (II) with carbon monoxide and hydrogen to form a mixture consisting mainly of 3-, 4- and 5-formylvalerates (III); hydrogenating this mixture and separating (I) from the mixture of alkyl 6C hydroxycarboxylates (IV) produced. The first step is in presence of a rhodium compound and a tertiary organic polyphosphite (A) and the hydrogenation is in the presence of a catalyst containing at least one element of subgroup I or VI-VIII.
