Abstract: The invention relates to a method for purifying 1,4-butynediol, in which 1,4-butynediol is compressed to 50 to 1500 bar and is expanded, one waits for phase separation to end following the expansion process, and the bottom phase is eliminated. Also disclosed is a method for hydrogenating 1,4-butynediol into 1,4-butenediol and 1,4-butanediol with the aid of the purified 1,4-butynediol.

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.
