    Abstract: Method for producing 1,6-hexanediol by hydrogenation of oligo-and polyestersAbstractThe present invention relates to a process for hydrogenating oligo-and/or polyestersobtainable by esterifying a DCS with a diol or diol mixture, said hydrogenation being performed in the presence of a catalyst whose catalyst precursor comprises copperoxide, aluminum oxide and at least one oxide of lanthanum, of iron, of tungsten, of molybderum, of titanium or of zirconium, and to a process for preparing 1,6-hexanediolby catalytically hydrogenating ester mixtures which comprise, as main components,oligo- and polyesters of a adipic acid and 6-hydroxycaproic acid, and are obtained byesterifying DCS with diois, especially 1,6-hexanediol or diol mixtures.No suitable figure
