Abstract: 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 (C20 < 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.
