Abstract
Infrared (IR) spectroscopic investigations were performed of the adsor ption and surface reactions of CH3Cl over acidic, basic and neutral ze olite catalysts. In each case, the spectral changes reflected the appe arance of the Fermi resonance phenomenon. The resonance parameters det ermined pointed to a decreasing extent of resonance in consequence of the adsorption. No influence of the acidity of the adsorbents was obse rved. The formation and consumption of HCl and OH groups were establis hed at elevated temperatures. The reactions assumed to have occurred a re described and explained.
