    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing hexanediol-1,6 from a carboxylic acid mixture.
    SOLUTION: In the method, (a) the carboxylic acids contained in an aqueous dicarboxylic acid mixture are converted to the corresponding carboxylic acid esters by using a low-molecular weight alcohol, (b) the obtained esterification mixture is separated from the excess alcohol and low-boiling point components in a first distillation stage, (c) the bottom products are fractionated in a second distillation stage into an ester fraction essentially free of 1,4-cyclohexanediol and a fraction comprising at least the major part of the 1,4-cyclohexanediol, (d) the ester fraction substantially free of 1,4-cyclohexanediol is catalytically hydrogenated, and (e) 1,6-hexanediol is obtained in a rectification stage from the hydrogenated discharge in a known manner. Thereby, high purity 1,6-hexanediol is made obtainable from waste products in a high yield.
