Abstract:
The invention relates to a method for producing hexamethylenediamine, wherein a) a muconic acid starting material is provided, which is selected from among 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 in order to form 1,6-hexanediol, and c) the 1,6-hexanediol obtained in step b) is subjected to amination in the presence of an amination catalyst in order to obtain hexamethylenediamine. The invention further relates to hexamethylenediamine which can be produced by means of said method.
