Abstract: The invention relates to a method for producing hexanediol by hydrogenating adipic acid dialkyl esters or mixtures containing adipic acid dialkyl esters as an essential constituent and organic halogen compound s as impurities. According to said method, the adipic acid dialkyl esters or the mixtures containing adipic acid dialkyl esters are guided over copper catalysts at a temperature of 50 to 250 .degree.C and at a pressure of 1 to 100 bar before hydrogenation in order to remove the organ ic halogen compounds. Said copper catalysts contain 0.5 to 80 wt. % copper calculated as CuO and have a surface of 5 to 1500 m2/g, 0.05 to 1.5 cm3/g porosity and a copper surface of 0.1 to 20 m2/g.
