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 either during fractionation of the esterification mixture or finally from the caprolactone.

Abstract: The invention relates to a method for the hydrogenation of oligo- and/or polyesters which can be obtained by the esterification of a dicarboxylic acid solution with a diol or diol mixture, the hydrogenation being carried out in the presence of a catalyst, the precursor of said catalyst containing copper oxide, aluminum oxide and at least one oxide of lanthanum, iron, tungsten, molybdenum, titanium or zirconium. The invention also relates to a method for producing 1,6-hexanediol by the catalytic hydrogenation of ester mixtures which contain oligo- and polyesters of the adipic acid and 6-hydroxycaproic acid as the main components and which can be obtained by the esterification of a dicarboxylic acid solution with diols and especially 1,6-hexanediol or diol mixtures.
