Hydrogenolysis of glycerol over Pt/C catalyst in combination with alkali metal hydroxides

Open Chemistry, 2016
The hydrogenolysis of glycerol was performed over a Pt/C catalyst in combination with several alkali metal hydroxides and their salts. LiOH was found to be an effective promoter for the selective hydrogenolysis of glycerol to 1,2-propanediol.
