Synthesis of Methyl Modified Mesoporous Silica MCM-41

Modification of mesoporous molecular sieve MCM-41 with dimethyl dichlorosilane,OctyltrimethOxysiIane and octadecyltrichlorosilane,the organic functional group was successfully grafted into the surfance of MCM-41 mesoporous sieve,the organic-inorganic complex material R-MCM-41 was synthesized and characterized by elemental analysis and FT-IR.The results of the characterization show that the organic functional group gets into the wall of the mesoporous MCM-41.
