| Abstract: | 1,2-Propanediol was prepared by hydrogenolysis of glycerol in the presence of Raney-Ni.Single factor experiment was introduced to observe the effects on result under different conditions.The most suitable conditions were determined as follows.The mass ratio of catalytst and glycerol is 35%,the reaction temperature is 170℃,the reaction time is 9h,water is used as solvent and concentration of glycerol is 80%,initial hydrogen pressure is 2.5MPa and stirring rate is 300r/min. |
| Keywords: | 1 2-propanediol glycerol Raney-Ni catalytic hydrogenolysis |
