Reaction Steps

20 wt % glycerol was hydrogenated at 500 psi hydrogen pressure at 220° C. using 80 g of water as solvent. 0.01 g/ml catalyst of 3% Pt/C catalyzed the reaction in 5 h to give glycerol conversion of 32% with 91% selectivity to 1,2-propylene glycol, 2% to acetol and 7% ethylene glycol and <0.01% other products.
