Abstract
The reaction of carbon tetrachloride with zeolites exchanged with alka li metal ions was investigated by means of in situ infrared and multin uclear magnetic resonance spectroscopy. Phosgene as reaction intermedi ate was proven; its formation is influenced by the temperature over th e different ion-exchanged samples. For the infrared spectroscopic meas urements, a reaction-induced Fermi resonance phenomenon was observed a nd is discussed. On the basis of the experimentally proven reaction in termediates, a detailed mechanism is suggested for the reaction of car bon tetrachloride with zeolites.
