摘要
本文用循环法测定了四氢呋喃一环己烷二元体系和四氢呋喃一环已烷一水三元体系在101.32kPa压力下的汽液平衡数据。分别用积分法(面积法)和微分法(点检验法)对二元实验数据做热力学一致性检验,均符合热力学一致性。 用非线性最小二乘法拟合了NRTL方程的二元交互作用能量参数,推算的泡点温度和汽相组成与实验值符合很好。
Vapor-Liquid equilibrum at 101. 32kPa pressure were measured by circulation method for tel- rahydrofuran-cyclohexane binary system and tetrahydrofuran-cyclohexane water ternary system. The consistence of the VLE data in the binary system has been checked by the differential test (area method), and integral test (point method), respectively, it has been found that the data are thermodynamically consistent. By the nonlinear least-squares method, the binary interaction energy parameters of NRTL equation were fitted from the experimental data of two binary systems. Bubble temperatures and vapor compositions predicted were shown a good agreement with the experimental data.
