The invention starts from a carboxylic acid mixture obtained as a byproduct of the catalytic oxidation of cyclohexanone / cyclohexanol of cyclohexane with oxygen or an oxygen containing gas, preferably with a purity of at least 99.5%, in particular substantially A process for preparing 1,6-hexanediol free from 1,4-cyclohexanediol, comprising the steps of extracting the reaction mixture with water, hydrogenating the carboxylic acid mixture, and esterifying and hydrogenating the feeder with hexanediol. It is about. |
