The second virial coefficient of tetrafluoromethane

Kletsky A. V., Mitropov V.V.


Abstract
The equation for the second virial coefficient of the R14 refrigerant is presented as a function of temperature. Deviations between the values of the second virial coefficient obtained from the experimental data and calculations using this equation within the temperature range of –70 оС to 500 оС are, as a rule, less than 1 cm3/mol.

Keywords: second virial coefficient, tetrafluoromethane.
