Abstract
Dichloropropanol was synthesized by chlorination of glycerol with hydrogen chloride under catalysis of organic acids and self-made inorganic catalyst. The qualitative analysis of by-products was carried out by GC-MS and the side reaction mechanism of catalytic reaction of glycerol by carboxylic acid was studied. And the main by-products of carboxylic glycerin ester, autopolymer of carboxylic acid, carboxylic chloropropyl ester and diglycerine were identified. The advantages and disadvantages between organic acids catalyst and inorganic catalyst on chlorination of glycerol were compared, and the results showed that the total selectivity of monochloropropanediol and dichloropropanol was obtained to above 99%, being 4% higher than that of organic acid catalysis.
