実験手順
The present invention relates to a process for preparing 1,6-hexanediol having a purity of at least 99% which is, in particular, essentially free of 1,4-cyclohexanediols, from a carboxylic acid mixture which is obtained in the oxidation of cyclohexane to cyclohexanone/cyclohexanol using oxygen or oxygen-containing gases by water extraction of the reaction mixture, by esterification of the acids, fractionation of the esterification mixture into an ester fraction free of 1,4-cyclohexanediols and a fraction comprising the 1,4-cyclohexanediols, hydrogenation of the ester fraction and purification of the 1,6-hexanediol by distillation.
