The influence of solvents was studied on coal tar, as a system. The possibility was investigated of separating the primary quinoline insoluble compounds, changing the physical and chemical properties and group composition of tar extraction cleaning. Technological conditions of extraction cleaning of tar and producing imp equation pitch were experimentally found from the pure raw material (soft pitch). Technical concepts were developed for a project of an experimental-industrial unit for deep cleaning of coal tar and production of impregnation pitch on its basis.
