| Abstract |
The paper discusses results of the measurement and estimation of the physical properties of fluorinated propane derivatives as second generation alternatives for currently used CFC and HCFC chemicals. One fluorinated ether was also studied. A total of 22 compounds were investigated with boiling points of -34.6 to 76.7 C. The measured properties presented for these compounds are: melting point, boiling point, vapor pressure below the boiling point, heat of vaporization, critical properties (temperature, density, and pressure), liquid densities, and liquid-phase heat capacities. Measured vapor pressures are reported from below the boiling point to the critical point for two of these compounds: CF3OCF2H (b.p. = 34.6 C and Tc = 80.7 C) and CF3CHFCF2H (b.p. = 6.5 C and Tc = 141.1 C). Vapor pressures and liquid-phase densities were also measured for CFC-12 in order to judge the accuracy of the experimental methods used. The measured vapor pressures were also compared with vapor pressures estimated using modified corresponding states methods to evaluate the accuracy of the estimation methods. |
