Abstract: Dynamic behavior of surface complexes of 2-propanol on aluminia during adsorption and dehydration was studied using IR spectroscopy. Good agreement was found between the first-order rate constants of alkene formation in pulse-flow experiments and that of disappearance of a reactive surface complex. It was shown that the simple surface alkoxide 2-Pr-O-Al remains on the surface constant temperature, but it can be completely removed by hydrolysis, or by heating up to 200 °C. The surface carboxylates are formed very slowly and are stable even in the presence of water vapour at 300 °C.
