Pj. Mcelroy, EXCESS AND UNLIKE-INTERACTION 2ND VIRIAL-COEFFICIENTS AND EXCESS MOLAR ENTHALPY OF A REFRIGERANT MIXTURE - (0.500CH(2)FCF(3)+0.500C(3)H(8)), Journal of Chemical Thermodynamics, 27(9), 1995, pp. 1047-1052
The excess second virial coefficient for (1,1,1,2-tetrafluoroethane propane) has been measured at temperatures of 299.5K, 313.15K, 328.15K
, and 343.15K, using the pressure-change-on-mixing method. The excess
enthalpy and unlike-interaction second virial coefficients are also re
ported. The results have been correlated using the Tsonopoulos equatio
n for virial coefficients. (C) 1995 Academic Press Limited.
