The second virial coefficients of ethane and its fluoroderivatives

Kletsky A. V., Mitropov V.V.

Abstract
The general equation for second virial coefficients of ethane and refrigerants R161, R152a, R143a, R134a, R125, R116 is presented as function of temperature, molar mass and dipole moment. The deviations between the values of second virial coefficient derived from experimental date and calculated using this equation are as a rule less than 2 %.

Keywords: second virial coefficient, refrigerant, dipole moment.
