The copper containing catalysts were prepared by reduction of various oxide precursor compounds. Their catalytic properties were studied in the hydrogenation of lactic acid to propylene glycol under atmospheric pressure. An efficient catalyst, whose precursor compound is copper hydroxosilicate with the structure close to the natural mineral chrysocolla, was developed. The optimum conditions for the synthesis of propylene glycol were established that make it possible to achieve a conversion of lactic acid of 97% at atmospheric hydrogen pressure and the temperature 473 K.
