Abstract:
The present invention relates to a process for the preparation of the hydroxyacetone or 1,2 propylene glycol. More particularly, the present invention relates to a process for preparation of hydroxyacetone or 1,2 propylene glycol by glycerol. Further, the said process is catalyzed by metal catalysts that results in 80 to 100% selectivity towards conversion of glycerol to hydroxyacetone (acetol) or 1,2 propylene glycol (1,2 PG).
