Isomerization of saturated hydrocarbons Communication 3. Isomerizations of cycloalkanes

Abstract

1. The isomerization of C6–C9 cycloalkanes was carried out in presence of a multifunctional catalyst and of hydrogen under pressure. 2. The compositions of the isomerization products from C7 and C8 cycloalkanes were in good agreement with the calculated thermodynamic values. 3. A mechanism was proposed for the isomerization of cycloalkanes. It is considered that, as in the case of the isomerization of paraffins, the first stage of the reaction is the formation of unsaturated hydrocarbons. 4. The effects of pressure and temperature on the course of the reactions of cycloalkanes in presence of multifunctional catalysts were demonstrated.
