Reaction Steps

20 wt % glycerol was dehydrated at nitrogen ambient pressure at 220° C. using 80 g of 2-propanol as solvent. 0.01 g/ml of 13% Cu+7% Cr+80% SiO2 catalyzed the reaction for 3 h to give glycerol conversion of 8% with 100% selectivity to hydroxyacetone, <0.01% 1,2-propylene glycol, <0.01% ethylene glycol and <0.01% to other products.
