Abstract: The invention relates to methods for producing 1,6-hexanediol and very pure e-caprolactone from a dicarboxylic acid solution (DCL), comprising steps (a) esterification of the DCL with alcohols, (b) partial catalytic hydrogenation of the esters, (c) separation by distillation of 1,6-hexanediol and low-boiling fractions as a top product, and (d) cyclization of the 6-hydroxycaproic acid ester contained in the bottom fraction in the presence of an alcohol boiling at a temperature exceeding the boiling point of caprolactane.

Abstract: The invention relates to a method for producing 1,6-hexanediol and caprolactone, preferably of at least 99.5% purity, which are especially substantially free from 1,4 cyclohexanediols, starting from a carboxylic acid mixture which is obtained as a byproduct of the catalytic oxidation of cyclohexane to cyclohexanone/cyclohexanol with oxygen or gases containing oxygen and by extraction of the reaction mixture with water, and by hydrogenation of the carboxylic acid mixture, esterification and hydrogenation of a partial flow to hexanediol and cyclization of 6-hydroxycaproic ester, the 1,4-cyclohexanediols being removed during fractionation of the esterification mixture or finally from the caprolactone.
