Аннотация: The influence of added anthracene on the yield and composition of thermal-filtration products from clinkering bituminous coal is investigated in the laboratory. It is found to increase the yield of the nonvolatile liquid thermal-filtration products responsible for clinkering; to change the structural and group composition of hexane extracts; and to change the relative quantity of structural groups determined by IR spectroscopy. These effects of anthracene may be attributed to the destruction of ester bridges in the initial coal; the formation of new and more stable esters; change in the packing of the aromatic rings; and redistribution of hydrogen in the system on heating. These processes lead to the formation of a liquid-crystal mesophase.
