Abstract

1,6-Hexanediols are prepared by hydrogenolysis in the liquid phase of polyesters containing up to 40 recurrent groups of general formula <FORM:1120427/C2/1> where R represents a hydrogen atom, a C1- 6 alkyl radical or a cycloalkyl radical, in the presence of an ester hydrogenolysis catalyst, particularly copper chromite, under conditions known for hydrogenolysis, particularly under a pressure of at least 150 atm. and at a temperature between 200 DEG and 300 DEG C. Examples describe the production of 1,6-hexanediol.
