本研究採用一套靜態式液相循環的相平衡裝置，量測甲苯+甲基甲醯胺雙成分混合物之汽液平衡數據，溫度範圍為372.59 K到412.36 K實驗結果顯示此雙成分系統無共沸物產生，且為正偏差。純質甲苯之飽和蒸氣壓數據用Antoine方程式迴歸，其平均絕對誤差在0.3 ％內。所量取的雙成分汽液平衡數據可使用NRTL與UNIQUAC模式準確地關聯。本研究也依據文獻數據訂定由芳香烴分離程序中主要成份所組成之雙成分配對的NRTL與UNIQUAC模式參數最適值。

A static-type apparatus with a liquid-phase circulation loop was used to measure isothermal vapor-liquid equilibrium (VLE) data for the binary system of toluene + N-methylformamide at temperatures from 372.59 K to 412.36 K. The experimental results exhibited no azeotrope formation and positive deviation from the ideal solution. The Antoine equation fitted the vapor pressure data of toluene to within an average absolute percentage deviation of 0.3 ％. The binary VLE data were correlated satisfactorily with the NRTL and the UNIQUAC models. Additionally, the optimal binary parameters of the NRTL and the UNIQUAC models were also determined from literature data for the pairs composed of the major components encountered in aromatics separation processes.
