Abstract

Multinuclear (23Na, 27Al, 29Si, 13C) MAS NMR techniques were used for investigation of surface reaction of Y-type zeolites with CFCs (CCl4, CCl3F, CCl2F2, CClF3, CF4) and HCFC (CHClF2). The hydrogen containing derivative reacts slowly. Those possessing more than 2 F atoms can be regarded as stable unreactive materials, CCl4, CCl3F, CCl2F2 react strongly with the zeolites. The reaction of HCFC with zeolites has a different mechanism to the other CFCs tested. On the basis of multinuclear NMR results a mechanism is given for the decomposition of HCFC.
