ABSTRACT:
A method of producing aliphatic and cycloaliphatic diols by catalytic hydrogenation of dicarboxylic acid esters by the use of a copper chromite catalyst in which the copper content (calculated as CuO) is 40-47 wt. %, and the chromium content (calculated as Cr.sub.2 O.sub.3) is 40-47 wt. %, and barium is also present in the amount of up to 10 wt. % (calculated as BaO) under mild temperature and pressure conditions is disclosed. The method produces diols without the formation of high boiling materials and does not require purification of the product diols by overhead distillation.
