EXTRACTION AND COMPONENT COMPOSITION OF COAL FROM MAIKUBEN DEPOSIT
Keywords:
coal, extraction, extractable substances, coal quality, solvent, IR spectroscopyAbstract
This article discusses the production of important organic compounds by extracting coal from the Maikuben deposit using various solvents such as benzene and hexane. For the first time, the composition of extracts was studied by IR spectroscopic method. As a result of IR spectroscopic study of hexane and benzene extracts, saturated, unsaturated, aromatic compounds, and amines were determined. A comparative analysis of benzene and hexane extract was made.
