摘要：

We present measurements of second virial coefficients of the chlorofluorocarbons R12 (CCl2F2), R22 (CHClF2), R114 (CClF2-CClF2), R134a (CH2F-CF3), R142b (CH3-CClF2), R152a (CH3-CHF2) and of the binary mixtures R12/R22, R22/R114, R22/R142b, R22/R152a,and R134a/R152a in the temperature range from 296 K to 475 K. The data are combined with earlier measurements of the same systems at low temperatures (J. Chem. Thermodyn. 23, 281 (1991)) for a critical discussion on the basis of the Stockmayer intermolecular potential model.
