• The effect of tetrabutylammonium acetate (TBAA) addition on the aggregation of heavy coal extract component; pyridine insoluble (PI) from the extraction of Upper Freeport (UF) coal with carbon disulfide-N-methyl-2-pyrrolidinone (CS_2-NMP) mixed solvent (1:1 by volume) was investigated. PI is partially insoluble in the mixed solvent, but the addition of a small amount of TBAA, the almost entire PI molecules become soluble in the mixed solvent. Recovered PI (PI-1) obtained by the removal of CS_2, NMP and TBAA from the solution was found to become almost completely soluble in the mixed solvent and NMP. The dissolution mechanism was discussed from the change of the aggregation state of PI at solution and solid states.
