Abstract
The rates of dehydrogenation of a series of 2-alkanols, the selectivity of the decomposition of 3,3-dimethyl-2-butanol, adsorption heats of diethyl ether by gas chromatographic method, crystallite size, total water content and surface concentration of hydroxyl groups were measured with six samples of chromium(III) oxide differing in the method of preparation. Correlation of the results showed that the catalytic properties of chromium oxide depend mainly on its temperature of calcination which governs the surface concentration of hydroxyl groups and the state of coordination of surface Cr 3+ ions.
