ABSTRACT: Novel essentially distinct from already known (methods of hydrogenation of fullerenes (C60 and
C70) or fullerite) method for the synthesis of highly hydrogenated carbon molecules is developed;
such approach is perspective hydrogen capacity accumulators. First, the reactionary conditions
are created for the realization of the process of fullerenization as direct transformation of molecules
of aromatic hydrocarbons, pyridine and ethanol into carbon molecules, fulleranes
(С60Н8-С60Н60 and С70Н8-С70Н44) and quasi-fulleranes (CnHn-6-CnHn-2 (n = 20 - 46)) containing up to
5.7 wt% hydrogen. X-ray amorphous powders of hydrogenated carbon molecules in gram amounts
are obtained. Appreciable dehydrogenation of such samples of fulleranes and quasi-fulleranes at
~50°C is began, while dehydrogenation of synthesized from fullerene (or fullerite) fulleranes is
observed only at temperatures above 400°C. Methods of NMR, IR spectroscopy, mass spectrometry
MALDI and temperature-programmed desorption mass spectrometry EI are used for the study of
condensed products of fullerenization of precursors molecules.
