摘　　要：用静态总压法实测了丙烯酸-醋酸二元体系在313.15~353.15 K下等温汽液相平衡数据,用W ilson和NRTL活度系数模型关联了实验数据,结果表明,实验数据可靠,两个模型拟合精度均良好。Isothermal vapor-liquid equilibria for binary system of acrylic acid and acetic acid have been measured at five temperatures in the range of 313.15 K to 353.15K by using static total pressure method.The experimental data were correlated with the Wilson and NRTL activity coefficient models and the modified Peng-Robinson equation of state.Good agreement between the experimental and correlated results is achieved.
