  • Abstract
    A vapor liquid equilibrium apparatus has been developed and used to obtain data for the binary HFC-143a+HFC-134a system. Fifty-four equilibrium data are obtained for the HFC-143a+HFC-134a system over the temperature range from 263.15 to 313.15 K at 10 K iIntervals. The experimental data were correlated with the Carnahan Starling De Santis (CSD) and Peng Robinson (PR) equations of state. Based upon the present data, the binary iInteraction parameters for the CSD and PR equations of state were calculated for six isotherms for the HFC-143a+HFC-134a system. The binary iInteraction parameters for both equations of state were fitted by a linear equation as a function of temperature. The present data were in good agreement with the calculated results from the CSD equation of state, and the deviations were less than 1.00 with the exception of two points.
