Abstract The saturated vapor pressure of phenylphosphorus dichloride was measured by static method,and the results were fitted to the Antoine equation and its Antoine coefficients were obtained.The boiling temperatures at atmospheric pressure,over the entire composition range, were measured for the binary system of phosphorus trichloride(1)-phenylphosphorus dichloride(2) by using a standard Swietoslawski type ebulliometer.The experimental t-x data were used to calculate infinite dilution activity coefficient,Wilson equation was used as regression equation to obtain Wilson parameter.The isothermal vapor-liquid equilibria data were deduced.
