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.
