Description: The action of organic solvents on a sub-bituminous coal has been examined over the temperature range of 150-350°C. The solvents studied included benzene, tetralin, pyridine, quinoline, piperidine, and ethylenediamine. The yield of extracted material varied widely with solvent and temperature, exceeding 60% (daf) for ethylenediamine at 250°C. The extracts were anlayzed for molecular weight, elemental composition and proton aromaticity. When mixtures of strong amine-type solvents with toluene were used, the yield of extract was linearly related mol fraction of strong solvent in the mixture.
