Abstract: The invention relates to a method for producing 1,6-hexanediol, preferably of at least 99% purity, and especially practically free from 1,4-cyclohexanediols, from a carboxylic acid mixture that is obtained as a byproduct of the oxidation of cyclohexane to cyclohexanone/cyclohexanol using oxygen or oxygen-containing gases and by extraction of the reaction mixture with water, by transesterification and hydration to form hexanediol, the yield in valuable products being increased by adding a monomer or polymer polyol with at least three hydroxyl functional groups after a transesterification stage in which catalysts that contain at least one element of groups 3 to 14 are used.
