Carbon disulfide-N-methyl-2-pyrrolidinone (NMP) mixed solvent (1:1 by volume) has been found to give high extraction yields (40-80wt%, daf) for many bituminous coals at room temperature. The extracts obtained were fractionated with acetone and pyridine, into acetone soluble (AS), acetone insoluble, pyridine soluble (PS) and pyridine insoluble (PI) fractions, respectively. The part of PI fraction was found to become insoluble in the CS_2-NMP mixed solvent. The increase of the solubility of PI fraction by the addition of the compounds such as TCNQ, TCNE and p-phenylenediamine suggests that this insolubilization behavior may be ascribed to the association of PI fraction by non-covalent interactions. The nature of the non-covalent interactions will be discussed.
