Abstract
The influence of the temperature on the protonation of acetonitrile by acidic zeolites was studied by infrared spectroscopy. Acidity at room or low temperature was not correlated with the protonation temperature, but the zeolitic structure played an important role. A new technique is presented for the study of the acidity of solids under reaction conditions. A good correlation was obtained in a series of various zeolites between the catalytic activity in the cracking of n-hexane and the protonation temperature of acetonitrile.
