摘要

为了给甲基戊烯酮萃取脱酚过程的设计和开发提供数据支撑，采用液液平衡釜分别测出常压下30、40和50℃甲基戊烯酮-水-邻苯二酚体系的液液相平衡组成，并通过Hand方程、Bachman方程对结果进行可靠性检验，其相关性系数的平方均大于0.99。同时利用Aspen Plus软件选取NRTL模型对实验数据进行关联，得到该三元物系相应的热力学模型参数，并以此计算相应的相平衡组成，与实验数据对比两者间的相对均方根误差和绝对平均误差均为1%。因此，NRTL模型及其参数可准确描述该物系的相平衡行为。

Abstract

In the extraction process of catechol removal from waste water

mesityl oxide was used as solvent

in order to provide fundamental data for this design and development. Experimental LLE data for mesityl oxide-water-catechol ternary system were measured at 30

40 and 50℃ under atmospheric pressure. Meanwhile

the reliability of the experimental LLE data was ascertained via Hand and Bachman equation where all of the square of the linear correlation coefficients were greater than 0.99. On the other hand

the experimental data were correlated with the NRTL activity coefficient model by data regression system of Aspen Plus. Accordingly

binary interaction parameters of the ternary systems were obtained. As a result

the compositions of LLE were calculated and compared with the corresponding experimental data by using the regressed parameters.And the relative root mean square deviations (RMSD) and absolute mean deviations (AMD) were both less than 1%

which show that the NRTL model and the regressed parameters agree well with the phase equilibrium behavior of this system.
