The approach to the generalized representation of vapor-pressure curve is discussed on the basis of the experimental data of vapor pressure for eight halogenated hydrocarbons. With respect to the functional form of the generalized representation of vapor-pressure curve, the Pitzer expansion based on the principle of corresponding states with acentric factor was adopted. The coefficients in the representation have been determined by the least squares fitting to the experimental vapor pressure data for eight halogenated hydrocarbons mentioned above. The proposed generalized representation reproduces most of these data within a pressure deviation of plus or minus 1. 0%.
