Abstract: The invention relates to a method for preparing 1,6-hexanediol in which a) a muconic acid feedstock is provided that is selected from among muconic acid, muconic acid esters, muconic acid lactones, and mixtures thereof, b) the muconic acid feedstock is subjected to a reaction with hydrogen in the presence of at least one hydrogenation catalyst to obtain 1,6-hexanediol, and c) the output from the hydrogenation process in step b) is subjected to distillative separation so as to obtain 1,6-hexanediol.
