| Abstract: | The formation of carbon phases by reacting formaldehyde with sulfuric acid under hydrothermal conditions was studied. The final products of the reaction were found to be amorphous carbon, diamond-like carbon, α- and β-graphite phases, fullerenes C60 and C70, fullerites, carbolite, and chaoite. Hydrocarbons of various compositions were detected in reaction products, namely cyclic hydrocarbons, including aromatic ones, and naphthene hydrocarbons. A formation scheme is suggested for carbon structures. |
