The effect of chemical demineralization on solvent extraction characterization of coals was investigated from the pyridine or chloroform extractabilities and the changes of yield for each molecular weight distribution of the extracts. It was suggested that the non-covalent interactions in the coal structure were affected by the temperatures and concentrations in the hydrofluoric acid treatment.
