Abstract

The reaction of carbon tetrachloride with zeolites exchanged with alkali metal ions was investigated by means of in situ infrared and multinuclear magnetic resonance spectroscopy. Phosgene as reaction intermediate was proven; its formation is influenced by the temperature over the different ion-exchanged samples. For the infrared spectroscopic measurements, a reaction-induced Fermi resonance phenomenon was observed and is discussed. On the basis of the experimentally proven reaction intermediates, a detailed mechanism is suggested for the reaction of carbon tetrachloride with zeolites.
