1. A study of the transformations of n-hexane and 1-hexene under pulse conditions disclosed that the oxide Al2O3 has a very weak, while Ga2O3, and especially In2O3, have a strong aromatizing (dehydrogenation) and hydrogenation activity, but these are

In an investigation of aluminochromium catalysts in a pulsed system, it was found that the catalysts containing chromium only in the oxidation state 3 + do not catalyze the dehydrocyclization of paraffin hydrocarbons.

1. In the dehydrocyclization of n-hexane, both under pulse and under continuous conditions, in the presence of various oxide catalysts, the yield of hexenes is greater, and that of benzene is lower, in a hydrogen atmosphere than in the atmosphere of

1. Under pulse conditions, 1,3,5-hexatriene on silica gel at 300 and 450°, and on MgO at 450°, undergoes catalytic C5- and C6-cylization with the formation of methylcyclopentadienes and cyclohexadienes. The latter are dehydrogenated to benzene, par

1. Cyclohexadiene, bensene, and methylcyclopentadienes are mainly formed from the hexatriene in the presence of silica gel and Al2O3 at 300–450°C. Increase in temperature (from 550 to 1100°C) and in the length of calcination of the silica gel (1

1. The addition of an alkaline additive toγ-Al2O3 increases the yield of benzene from 1,3,5-hexatriene and 1,5-hexadiene. The yield of benzene from the hexadiene increases with increase in the basicity of the additive in the series: K2O, Rb2O, Cs2O,
