【摘要】 用UNIQUAC-HOC和NRTL-HOC模型计算了乙酸-水latm下的活度系数和逸度系数,乙酸-水在 298．15 K时的逸度系数。并与文献作了比较。以文献数据为基础数据,结合乙酸-水、乙酸-乙酸丁酯二元体系的参数,从三无数据中拟合出了水-乙酸丁酯之间的NRTL方程和UNIQUIC方程的相互作用参数。更多还原

【Abstract】 By dint of UNIQUAC - HOC and NRTL - HOC model, the fugacity coefficient and activity coefficient of the binary system acetic acid - water at atmosphere pressure was calculated, the fugacity coefficient of the system at 298. 15 K was calculated, which was compared with the data on the literature. With the interaction parameters of the binary system acetic acid - water and acetic acid - n - butyle acetate, The NRTL - HOC model and the UNIQUAC - HOC model was used to correlate the literature, and the interaction parameters of water- n - butyle acetate is gotten.更多还原
