Working principle of coal extraction by CS_2-NMP mixed solvent has been discussed based on the experimental data obtained from solvent swelling measurement and dielectric behaviors of coal. It was found that an equimolar complex formation between CS_2 and NMP was suggested to be responsible to increase the electron donorability of the solvent which was effective to destruct non-covalent network structure of coal such as charge-transfer bonding or π-π bonding interaction, and to increase the solubility toward coal extract.
