摘要：
The invention provides a process for preparing 1,2-propanediol, by reacting glycerol which has a purity of at least 95% by weight with hydrogen at a hydrogen pressure of from 20 to 100 bar and a temperature of from 180 to 240 DEG C. in the presence of a catalyst which comprises from 10 to 50% by weight of copper oxide and from 50 to 90% by weight of zinc oxide in an autoclave.
