Firstly the method of joint synthesis of carbon molecules and their hydrides is developed. The stage of high-temperature sublimation of carbon in a new method of generation of carbon molecules is completely excluded. By mass spectrometric method the condensation products of new method of pyrolysis (NMP) benzene are studied. Firstly clusters (C3-C17), typical for carbon vapour, in substances obtained under pyrolysis of hydrocarbons were detected. Fullerene C60 and its hydrides, quasi-fullerenes C48 and C33 inproducts of benzene pyrolysis are detected also. Firstly it is shown what clusters C3-C5 can be generated at so low (100?C-200?C) temperatures of decomposition of substance. Obtained experimental results firstly demonstrate that the small carbon molecules can be generated in reactionary conditions excluding evaporation of carbon. Dehydrogenation and destruction of hydrocarbon molecules is the first stage on a route of the transformation of benzene to carbon molecules.
