Abstract
The paper presents data for structural-group and component compositions of bitumoid fractions derived upon sequential extraction of brown coal of the Tyulgan deposit with the following solvents: ethanol, n-heptane, and alcohol-benzene. As demonstrated by FT-IR, 13C CPMAS NMR, and GC-MS, the resulting bitumen is a multicomponent mixture of compounds mainly consisting of alkanes, fatty alcohols, unsaturated hydrocarbons, aromatic compounds found in trace amounts, carboxylic acids, and phenols. Bioactive compounds, such as Lignoceic alcohol, Ceryl alcohol, Behenic alcohol, Ferruginol, β-Amyrin, and Heneicosane, were detected therein.
