摘要：

Measurements are reported of the excess second virial coefficient, ε [=B12 - 1/2(B11 + B22)] and interaction second virial coefficients are calculated for binary mixtures of the normal perfluorocarbons, perfluoromethane through perfluorohexane, at 50 and 100°. The results are well described by a Kihara spherical core potential using the geometric mean of the energy parameters. The applicability to these mixtures of a three-parameter corresponding states equation originally developed for hydrocarbons is discussed. The principle of congruence is approximately valid for the excess volumes and heats of mixing in these systems.
