The XRD and N2 sorption measurements suggested the preservation of ordered mesoporous structure; FTIR characterization indicated that the C/Sis were successfully modified with -COOH and the acidity of COOH-C/Si material was significantly enhanced. COOH-30C/Si(A) with high COOH density of 2.61mmol/g and retained mesoporous structure exhibited superior activity for dichlorohydrin production. Through the optimization of reaction variables, as high as 65.7%, the yield of DCH, can be achieved over COOH-30C/Si(A) after 12h reaction under 130°C. Meanwhile, it was 100% that the conversion of the glycerol can be reached. A significant issue, good durability, especially for practical application, was verified through five consecutive cycles with the optimal reaction variables.
