Specific features of n-hexane pyrolysis as a process for fullerenization of aliphatic hydrocarbon molecules

Specific features of the pyrolysis of n -hexane were studied as a process of fullerenization (750–1000°C) of molecules of saturated hydrocarbons. The specificity of the fullerenization process consists in that its products are formed throughout the reaction space, but are localized (deposited and co...

Description
Summary:Specific features of the pyrolysis of n -hexane were studied as a process of fullerenization (750–1000°C) of molecules of saturated hydrocarbons. The specificity of the fullerenization process consists in that its products are formed throughout the reaction space, but are localized (deposited and condensed) in its low-temperature zone. Fullerenization products of n -hexane, extracted from the pyrolytic carbon black in the form of hydrogenated carbon molecules containing up to 5.1% hydrogen, serve as a source of hydrogen in a wide temperature range (50–750°C). The condensed fullerenization products of n -hexane were studied by chemical, X-ray diffraction, and MALDI mass-spectrometric analyses, IR and NMR spectroscopy, and the method of temperature-programmed desorption with a mass-spectrometric analysis.
