Earlier small carbon molecules C₂- C₁₃ as cations and аnions in hot carbon plasma and flame gases were detected only. From large amount of quasi-fullerenes (C_{20 < n < 60}) revealed in mass spectra of carbon vapor only C₂₀ and C₃₆ were synthesized. Therefore problem of creation of new methods for synthesis of carbon molecules is considered extremely important. By us new reactionary conditions of pyrolysis of hydrocarbons, in particular benzene is developed. A main distinctive feature of this pyrolysis is opportunity of separate localization of condensed products and soot. Mass spectra of toluene and ethanol solutions of obtained products contain intensive peaks with m/z values appropriate anions of small molecules (C₃ – C₂₀), them hydrides (C₅H₂, C₁₀Н₄, C₁₄H₄, C₁₆H₈, C₁₈Н₂) and cations of molecules (C₆, C₇, C₁₅, C₁₇). For the first time in products of pyrolysis quasi-fullerenes C₄₀, C₄₈, C₅₂, C₅₄, C₅₆ and C₅₈ are found out. Thus, small carbon molecules and quasi-fullerenes in reactionary conditions excluding carbon evaporation can be formed.
