摘　　要：本文采用改进式罗斯平衡釜测定了在760.0mmHg压力下吡啶-二甲基甲酰胺(以下简称DMF)的汽液平衡数据。用Wilson方程、NRTL方程、Raoult定律和汽相加以校正等方法关联,证明该二元体系液相可作为理想溶液。汽相可作为理想气体处理。The isobaric Vapor-liquid equilibrium data of pyridine and dimethylformamide binary system were determined at 760. 0 mm Hg with modified Rose equilibrium still. The experimental data were correlated by Wilson equation, NRTL equation and Raoult' s law. The results showed that the liquid phase could be considered as ideal solution, and the vapor phase, as ideal gas mixture in the binary system.
