| 摘 要： | 本文以改进的Ｒｏｓｅ平衡釜，测定了在７００ｍｍＨｇ柱下的正庚烷－甲苯二元体系汽液平衡数据。用Ｈｅｒｒｉｏｇｔｏ的半经验方法对测定数据进行了恒压下的热力学一致性的校验，采用Ｖａｎ Ｌａａｒ， Ｍａｒｇｕｌｅｓ及Ｗｉｌｓｏｎ方程以“汽相组成误差平方和”为目标函数，用非线性最小二乘法在ＡＰＰＬＥ －Ⅱ微机上进行了热力学关联，三个方程拟合精度都甚好。

| Abstract: | Vapor-Liquid equilibrium for the binary system of n-Heptane-Toluene were determined at 760mmHg with a modified Rose equilibrium still Thermo- dynamic consistency for the data at the given prussure were tested by Herri- ngton's semiempirical method.Van Lean,Margules and wilson equations were employed to correlate V-L-E data of the system by nonlinear least square method on a mini-computer(APPLE-II), and all represented satisfy- ing results with good accuracy. |
