Abstract
The polymeric character and micellar structure of coal were reviewed from the standpoint of the interaction between solvent and coal. The molecular weight per crossed unit of coal was found to be an important factor for determining not only the chemical structure but also the physical pproperties of coal. The cohesive energy density, i. e. , solubility parameter of coal, was estimated from solvent extraction or swelling equilibrium with solvent. It is stressed that the physical-chemical behaviors described are correlated with compatibility between coal, coal blends and solvent.
