The invention relates to a process for preparing hexane-1,6-diol, in which
a) a muconic acid starting material is provided, selected from muconic acid, esters of muconic acid, lactones of muconic acid and mixtures thereof,
b) the muconic acid starting material is subjected to a reaction with hydrogen in the presence of at least one hydrogenation catalyst to hexane-1,6-diol, and
c) the output from the hydrogenation in step b) is subjected to a distillative separation to obtain hexane-1,6-diol.
该发明涉及一种制备己烷-1,6-二醇的过程,其中a) 提供一种丁二酸起始物,所述丁二酸起始物选自丁二酸、丁二酸酯、丁二酸内酯及其混合物,b) 在至少一种加氢催化剂的存在下,将丁二酸起始物与氢气反应以得到己烷-1,6-二醇,c) 将步骤b)中加氢反应的产物进行蒸馏分离,以获得己烷-1,6-二醇。
