【 摘 要 】

An inorgano�?�organic ion exchanger, Sn(IV) phenyl phosphonate, has been synthesized in amorphous form. Further, an attempt has been made to synthesize Sn(IV) phenyl phosphonate in the nano form. The materials have been characterized for elemental analysis (ICP�?�AES), thermal analysis (TGA), X-ray analysis and FTIR spectroscopy. Chemical resistivity of these materials has been accessed in acidic, basic and organic solvent media. Catalytic activity has been studied and compared by using esterification of ethylene glycol as a model reaction wherein glycoldiacetate has been prepared. The transport properties of these materials have been explored by measuring specific proton conduction at different temperatures using SOLARTRON DATASET impedance analyser over a frequency range 1 Hz�??1 MHz. It has been observed that Sn(IV) phenyl phosphate in the nano form behaves as a better Bronsted catalyst and proton conductor as compared to the amorphous form.
