由（乙酸丙酯 + 2-甲基丁-1-醇）、（乙酸丙酯 + 1-己醇）和（乙酸丙酯 + 1-庚烷）形成的二元系统的等压气液平衡 (VLE) 数据已在 101.3 kPa 压力下使用平衡蒸馏器测定。实验数据通过Herington半经验方法进行检验，热力学一致性良好。活度系数与非随机二液 (NRTL)、Wilson 和通用准化学 (UNIQUAC) 模型相关。此外，还使用 UNIQUAC 官能团活性系数 (Do) 模型来关联 VLE 数据。与所有三个二元系统中的其他三个模型相比，NRTL 模型显示出稍微更好的结果。
Isobaric vapor–liquid equilibrium (VLE) data for the binary systems formed by (propyl acetate +2-methylbutan-1-ol), (propyl acetate + hexan-1-ol), and (propyl acetate + heptan-1-ol) have been determined at the pressure of 101.3 kPa using an equilibrium still. The experimental data were checked through the semiempirical methods of Herington, and the thermodynamic consistency was satisfactory. The activity coefficients were correlated with the nonrandom two liquid (NRTL), Wilson, and universal quasichemical (UNIQUAC) models. In addition, the UNIQUAC functional-group activity coefficients (Do) model was used to correlate the VLE data. The NRTL model shows slightly better results compared with other three models among all three binary systems.
