Conclusions

  1. 1.

    In an inert medium (N2) under pressure at 480°C in the presence of H forms of pentasils, benzene undergoes decomposition and self-alkylation with the predominant formation of liquid products of the reaction, mononuclear alkyl aromatic hydrocarbons and naphthalene, with a high degree of conversion (>70%).

  2. 2.

    The degree of conversion and selectivity of the reaction are determiend by the SiO2/Al2O3 ratio of the zeolite to a significant degree: when the modulus increases from 35 to 140, conversion of benzene and the yield of products of alkylation decrease by 2–3 times; benzene undergoes no conversions on Na-pentasil.

  3. 3.

    It was hypothesized that the pathways of conversion of benzene differ in an inert medium and in H2.
