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 71% Cu+Cr; 19% Al; 10% Ba catalyzed the reaction for 3 h to give glycerol conversion of 34% with 90% selectivity to hydroxyacetone, 8% 1,2-propylene glycol, <2% ethylene glycol and <0.01% to other products.
