METHOD FOR THE PRODUCTION OF 1,2-ETHYLENE GLYCOL AND 1,2-PROPYLENE GLYCOL BY HETEROGENEOUSLY CATALYZED HYDROGENOLYSIS OF A POLYOL

摘要

The invention relates to a method for producing a 1,2-ethylene glycol and 1,2-propylene glycol by heterogeneously catalyzed hydrogenolysis of a polyol, wherein a catalyst comprising rhodium (Rh) is used as a heterogeneous catalyst and a carrier material, selected from the group of carbon, zirconium dioxide, titanium dioxide and calcium carbonate is used, wherein the catalyst does not comprise ruthenium (Ru).
