Catalytic transformations of individual naphthene hydrocarbons and cyclohexene in presence of benzene

1. An investigation was made of the transformations of some individual naphthene hydrocarbons and of cyclohexene in presence of benzene over synthetic aluminum silicates. 2. At 525–530° and 10–15 atm, the transformations of these cyclic hydrocarbons in presence of benzene are directed mainly toward the formation of aromatic hydrocarbons of low molecular weight: toluene, xylenes, and others. The presence of benzene has a favorable effect on the aromatization of cyclohexanes and cyclohexene. 3. In the catalytic treatment of naphthenes, aromatization is accompanied, to some extent, by the destructive alkylation of benzene and by the cracking and isomerization of the original cycloalkanes.
