1. An investigation of oxidative dehydrogenation of cyclohexane on X zeolites has revealed that the character of the reaction on the initial NaX zeolite differs from that observed for the other cation and cation-decationized forms of zeolites investigated. On zeolites with a low degree of exchange we mainly observe severe oxidation, and the degree of oxidative dehydrogenation to benzene increases as the sodium ion content of the zeolite decreases. 2. The activity of zeolite catalysts in this reaction depends on the nature and the degree of exchange for the multiply charged cation, and on the degree of decationization of the cation-decationized zeolite. Zeolites with minimal sodium cation content exhibit a higher selectivity with respect to benzene. 1977 Plenum Publishing Corporation.
