In the present work the catalytic reactions of a wide range of aliphatic and cyclic hydrocarbons in the presence of HS-borosilicate have been studied with the aim of elucidating the selectivity of the action of this catalyst with respect to hydrocarbons of differing composition and structure. High-silica (HS)-borosilicates exhibit a high catalytic activity in the aromatization of unsaturated hydrocarbons, including ethylene. A high selectivity in the action of HS-borosilicate with respect to C/sub 2/-C/sub 6/ hydrocarbons when compared with the corresponding alkanes and cyclanes has been revealed. HS-borosilicate is an active catalyst for the isomerization of cyclohexene into methylcyclopentene. The hypothesis is proposed that the aromatization of aliphatic and cyclic hydrocarbons in the presence of borosilicate takes place via a preliminary stage involving the formation of lower olefins.
