Abstract
The pyridine adsorption-desorption method, followed by IR spectroscopy , is generally applied for acidity determination of solid catalysts. A peculiar band at 1462 cm(-1) was observed by several authors upon pyr idine desorption at higher temperatures and was interpreted in various ways. A new complex between Lewis framework acid sites and pyridine i s proposed and several evidences are reported.
