| 摘 要： | 用动态－双沸点仪浊定了不同温度和不同盐浓度下甲醇－醋酸钠、水－硫酸钠的饱和蒸汽压力以及水－醋，酸－硫酸钠的汽液相平衡数据，提出了一个形似Antoine方程的饱和蒸汽压关联模型，用此模型对实验数据进行了关联，结果表明计算值能较好地与实验值相吻合，此模型成功地应用在水－酸－硫酸钠含盐溶液的汽液平衡关联中。

| Abstract: | Vapor pressures of CH 3OH-CH 3COONa and H 2O-Na 2SO 4 systems and the Vapor liquid equilibrium data of H 2O-CH 3COOH-Na 2SO 4 system were detected under different temperatures and salt concentrations. A model based on Antoine equation was established to calculate vapor pressures. The calculation and experimental results show that the model can be used to estimate the vapor pressure in salt solvent systems.It was successfully used to correlate the vapor liquid equilibrium of the H 2O-CH 3COOH-Na 2SO 4 system. |
