Reaction Steps
20 wt % glycerol was dehydrated at nitrogen ambient pressure at 220° C. using 80 g of water as solvent. 1 g of 50% Cu+50% Mg catalyst of nano size catalyzed the reaction to give glycerol conversion of 24% with 79% selectivity to hydroxyacetone, 20% to 1,2-propylene glycol and 1% to ethylene glycol.
