Abstract

Adsorption and decomposition of chlorofluorocarbons, with (CHClF2) and without (CCl2F2) hydrogen content were investigated on zeolites NaY and HZSM-5. The IR and 13C NMR spectroscopic results are in good agreement and proved that the intermediates of the surface reactions of CCl2F2 are CCl4 and COCl2, while the gaseous end-products are CO2 and HCl. For CHClF2 the intermediate is CHCl3, and the final gaseous products are CO and HCl. The fluorine content of both reactants is retained in the solid phase as AlF3.
