✦ Synopsis

Coal processed in a perfluorocarbon liquid at 250°C with low concentrations of additives may undergo chemical reactions, but does not dissolve. Under these conditions quinoline has little effect on coal, while 1,2,3,4_tetrahydroquinoline produces marked increases in coal solubility, presumably due to hydrogen donation. While the hydrogen requirements of a bituminous coal are satisfied by tetrahydroquinoline at a tetrahydroquinoline:

coal ratio of 0.2, for a lignitic coal, addition of gaseous hydrogen is necessary for substantial solubility increase.
