摘要
用经Ellis汽液平衡釜验证的自制汽液平衡装置测定了甲醇-正丁醇二元液系在不同温度处恒温时的压力与组成的汽液平衡数据,计算了体系的热力学函数,并进行了热力学一致性检验。这不仅为二元混合液系的压力组成测定提供了研究装置,同时充实了压力组成实验数据,还丰富了二元液系的热力学理论。
Vapor liquid equilibrium （VLE） pressure and composition of methanol and n-butanol binary system at different constant temperatures were determined in a self-made vapor-liquid equilibrium facility verified by Ellis still. Thermodynamics functions of the system were calculated. All experimental data passed the thermodynamic consistency tests. This study provides a measurement facility for determination of VLE pressure and composition data of binary systems, replenishes the VLE experimental data, and enriches the thermodynamic theory for liquid binary systems.
