Thermophysical properties of trifluoroiodomethane (CF3I)

Trifluoroiodomethane (CF 3I) is a new refrigerant, which is nonflammable, nontoxic and environmentally friendly. The new thermophysical property data of trifluoroiodomethane (CF 3I) developed by authors are summarized. Experimental data of critical parameters, and the correlations of saturated liquid and vapor density, enthalpy of vaporization, vapor pressure, pVT properties, second virial coefficient, ideal gas heat capacity, surface tension, viscosity and thermal conductivity are obtained in this paper. Literature data for the thermophysical property of CF 3I are compared with the present results. The correlations and experimental data published in this paper can be used for optioning refrigerants in engineering application.
