ABSTRACT

Hydrogenated carbon molecules are synthesized by a method which essentially is distinct from already known methods of preparation of fulleranes as this method a preliminary stage of synthesis of carbon molecules is excluded completely. Fulleranes and quasi-fulleranes as nanodimentional particles were in common deposited by ethanol from benzene-xylene extracts from products of pyrolysis of vapours of benzene and pyridine. The dehydrogenation of the synthesized samples of fulleranes and quasi-fulleranes is started at 30-50℃ and the evacuation of hydrogen proceeds up to 700℃. At thermolysis of nanopowders of fulleranes and quasi-fulleranes alongside with hydrogen are formed also hydrocarbons (methane, propane and butane), which are usually detected at defullerenization (disclosing and partial fragmentation of fullerene cage) fulleranes, synthesized at hydrogenation of fullerenes or fullerite. The contents of hydrogen in some quasi-fulleranes (C26H24, C28H22, C30H22) and fulleranes (C60H32, C60H46, C60H60) reaches 5.4–6.9 mass%. The first was detected by a mass spectrometric method the cluster С60Н60, the thin structure of which spectrum completely corresponds fullerane of equiatomic composition, С60Н60.
