Abstract

The grafting reaction of SnMe₄ onto the supercages of HY zeolite was studied under high vacuum conditionand the chemical composition and structure of resulting solid were characterized by in situ FT-IR,XRD,UV-Vis,DRS,DTG,DTA,N₂ adsorption,ICP,elemental analysis,and gas chromatography.The reaction could occur rapidly and quantitatively at low temperature down to 188 K(apparent active energy was 1014 kJ·mol^-1),resulting in the grafting of well-defined—Sn(CH₃)₃ fragments onto the surface of zeolite supercages.The grafted Y zeolite is quite different from the starting HY zeolite in adsorption properties,and showed obvious size-selectivity for hydrocarbons.

Key words: surface organometallic chemistry, tetramethyltin, Y zeolite, grafting reaction
