Title:
METHOD FOR PRODUCING 1,6-HEXANEDIOL BY HYDROGENATION OF OLIGO- AND POLYESTERS
Document Type and Number:
WIPO Patent Application WO/2010/115759
Kind Code:
A3
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.
