用沸点计间接测定甲醇-水系汽液平衡

Indirect Determination of the Vapor-Liquid Equilibrium of Methanol-Water System by Ebulliometry

本文用改进沸点计在压力为1.013×10~5P_a下测定甲醇-水系不同浓度下的沸点,用Tao经验公式计算在平衡条件下汽相组成,並与文献实验值进行比较,最后用Wilson等方程关联,得到满意的效果。

By means of a modified ebulliometer measures the poiling point of a methanol-water system in variable concentration at atmospheric pressure, Tao's empirical formula is used to calculate the vapor under epuilibrium condition. The results are being compared with that given in the literature and that solved by Milson equation. They are proved to be satisfactory.
