摘要：
The invention relates to a method for preparing 1,2-propanediol by reacting glycerol, which has a purity of at least 95 wt %, with hydrogen at a hydrogen pressure from 20 to 100 bar and a temperature from 180 to 240° C. in the presence of a catalyst, which comprises 20 to 60 wt % of copper oxide, 30 to 70 wt % of zinc oxide and 1 to 10 wt % manganese oxide in an autoclave.
