One of the widely used methods of studying the structure of combustible minerals is the investigation of the water-soluble products of their oxidation, which consist of an extremely complex mixture of substances, mainly mono- and polyfunctional water-soluble polycarboxylic acids. Results of an experimental study are presented in which the products of the reduction of the water-soluble polycarboxylic acids from Angren fusinitic brown coal has been analyzed by chromatography and UV spectroscopy. It is demonstrated that the carbon skeleton of the molecules of the substances investigated consists mainly of polycyclic aromatic hydrocarbons, together with which long-chain aliphatic hydrocarbons are also present. 12 refs.
