Abstract
Coal from the Kansk-Achinsk and South Ural basins and their extracts—humic acids, hymatomelanic acids, and bituminous resins—are studied by technical and elemental analysis, Fourier transform infrared (FTIR) spectroscopy, and 13C NMR spectroscopy. The bitumen composition is investigated by chromatography and mass spectrometry. Data are presented for the phytostimulant activity of hymatomelanic acids and their mixtures with the saponifiable component of the extracted bituminous resin with respect to Aphrodite wheat seeds. Such activity is established for the samples, whether used individually or in combination. The phytoactivity index (PI) is found to be in the range 1.09–1.20.
期刊介绍：
The journal publishes scientific developments and applications in the field of coal beneficiation and preparation for coking, coking processes, design of coking ovens and equipment, by-product recovery, automation of technological processes, ecology and economics. It also presents indispensable information on the scientific events devoted to thermal rectification, use of smokeless coal as an energy source, and manufacture of different liquid and solid chemical products.
