Based on investigation of differences between silylating MCM-41 with Cl3SiC6H4CH2Cl and with (EtO)3SiC6H4CH2Cl,the novel strategy was proposed that the mixture of Cl3SiC6H4CH2Cl and Cl3SiCH3 was used to silylate mesoporous molecular sieves MCM-41,introducing both hydrophobic methyl and cholorobenzyl groups in one pot,which was comfirmed by solid state NMR.It was found that Cl3SiCH3 with a small molecular size can be used as a thinner to adjust the loading of chlorobenzyl group on surface of mesoporous molecular sieves;the hydrothermal stability of chlorobenzyl functionalized MCM-41 was improved by introduction of methyl groups.

Key words: mesoporous molecular sieve, chlorobenzyl, organo-functionalized, hydrothermal stability
