| Abstract: | Vapor liquid equilibrium data were determined by means of an Ellis still at 101.325 kPa for acrylonitri le o -, or m -, or p -xylene, respectively. A thermodynamics model proposed by Hayden-O' connell for accounting the nonideal behavior of the vapor phase and liquid phase was used to calculate the activity coefficient of liquid phase. All the experimental data have been tested by the method proposed by Her ington and the results have shown that the experimental data conform to the dema nd of thermodynamic consistency. Wilson equation was selected to correct the com position and activity coefficient of the component in the liquid phase. The calc ulated values of the vapor composition are in good agreement with experimental data. |
