The silylated mesoporous molecular sieve was prepared via the organic-silylation of a pure silica KIT-1 with trimethylchlorosilane and dichlorodimethylsilane at 30℃ for 8 h,and characterized by means of FT-IR,XRD and nitrogen adsorption-desorption techniques.The FT-IR spectra show that the trimethylsilyl groups have been grafted to the surface of molecular sieve.Compared to the parent sieve,the resultant samples keep the original mesoporous structure with less specific BET surface area and BJH volume and smaller diameter of pores and show a higher stability toward water(boiling in water for 48 h,the sieve still remained the original mesoporous structure).The hydrophobicity of the sieve modified by trimethylchlorosilane is better than that of the one modified by dichlorodimethylsilane,its adsorption capacity for mixed cresol in dilution is 0.512 mmol/g.
