Separation methods for coal liquefaction products have received considerable attention recently for use as the raw materials of fine chemicals. The solubilities of 2,6-dimethylnaphthalene and 2,7-dimethylnaphthalene at 308.2 and 328.2 K and the solubilities of the binary mixture at 308.2 and 318.2 K in supercritical carbon dioxide were measured by a flow-type apparatus. The pressure range of measurement was about 8--25 MPa. The solubilities were correlated by a three-constant cubic equation of state with two characteristic parameters.
