摘要
A process for preparing 1,2-ethylene glycol and 1,2-propylene glycol by heterogeneously catalyzed hydrogenolysis of a polyol, which comprises using, as a heterogeneous catalyst, a catalyst comprising palladium (Pd) and a support material selected from the group of carbon, zirconium dioxide, titanium dioxide and calcium carbonate, the catalyst not comprising any ruthenium (Ru), and performing the hydrogenolysis in the presence of water.
