Abstract:
The adsorption of water and 2-propanol on alumina has been studied by means of IR spectroscopy. Low temperature adsorption of CO has revealed that evolution of Lewis acid sites begins at 80 °C in vacuo when still about 40% of molecular water is present on the surface. The thermodesorption of water proceeds by recombination of neighbouring OH groups. The adsorption of 2-propanol increases the concentration of the nonisolated OH groups and decreases the concentration of isolated ones. The irreversible adsorption influences mostly the C-O and Cβ-H bonds in 2-propanol.
