1.A study was made of the catalytic transformations of cyclohexene over aluminum silicates.2.At 300–350° at atmospheric pressure, about 60% of the cyclohexene is isomerized into methylcyclopentenes, which are then partially hydrogenated to methylcyclopentane. About 40% of the cyclohexene is dimerized, and the dimer is isomerized into hydrocarbons of the decalin and octalin series; subsequent isomerization, hydrogenolysis, and dehydrogenation of these lead to the formation of tetraalkylbenzenes and dialkylnaphthalenes as end products.3.On the basis of the study of the transformations of cyclohexene it is suggested that in the processing of petroleum products over aluminum silicates, together with other aromatization reactions, the transformations of unsaturated cyclic compounds play an important part.4.Of the hydrogen consumed in the course of the transformations of cyclohexene, 50–55% is accounted for by the polymeric compounds transformed in the process into aromatic and naphthalene hydrocarbons, and 45% is accounted for by coke-forming condensation products. |
