摘要:
在常压下使用单级循环汽液平衡釜对丙酮-乙腈-叔丁醇-水体系中丙酮-乙腈、丙酮-叔丁醇、乙腈-叔丁醇、乙腈-水的4组二元、丙酮-乙腈-叔丁醇、丙酮-叔丁醇-水、乙腈-叔丁醇-水的3组三元和丙酮-乙腈-叔丁醇-水的四元汽液平衡数据进行测定. 通过赫林顿积分法对二元汽液平衡数据进行热力学检验,进而考察本装置测定实验数据的可靠性和稳定性. 对测定的实验结果选用UNIQUAC和NRTL模型关联,与实验值对比,UNIQUAC模型关联值与实验值较为吻合,平均相对误差最大值小于3%. 同时,测定四元体系在乙二醇等4种萃取剂中的汽液平衡数据,为丙酮-乙腈-叔丁醇-水体系萃取分离提供基础数据.
Abstract:
In this paper,the vapor-liquid equilibrium(VLE)data of binary,ternary and quaternary systems in acetone-acetonitrile-tert-butanol-water system are measured by single-stage circulating vapor-liquid equilibrium pot at atmospheric pressure. The reliability and stability of the experimental data measured by this device are investigated by thermodynamic test of vapor-liquid equilibrium data of the six binary systems with Herrington integral method. Moreover,UNIQUAC and NRTL models are used for correlation of the measured results. The results show that UNIQUAC model associations are found to be in good agreement with the experimental values and the average relative error between the experimental value,and that calculated value is less than 3%. At the same time,the vapor-liquid equilibrium data of the quaternary system in ethylene glycol and other four extractants are investigated. This study not only fills in VLE database,but also provides the basic data for extraction separation of acetone-acetonitrile-tert-butanol-water system.
