本研究利用示差掃描熱量計 ( Differential Scanning Calorimetry, DSC ) 儀器量測N-phenylacetamide (1) + 4-aminoacetophenone (2)、N-phenylacetamide (1) + 3-hydroxyacetophenone (2)、N-phenyl- acetamide (1) + 4-hydroxyacetophenone (2) 等三種物質於一大氣壓下二成份系統之固液相平衡數據,結果顯示此三組固液相平衡圖形皆為簡單共熔型 ( simple eutectic ) 之圖形。本研究之目的在於提供目前文獻上缺乏之固液相平衡數據,這些相平衡數據不但可以幫助發展熱力學理論研究,也可以提供工業分離程序中之基本分離資料。
本研究利用Gray 熱分析數學模式,進而推出相轉化曲線 ( fractional transformation curve ) 及共熔點轉化率( eutectic fraction )。利用不同組成下之共熔點轉化率,即可求得混合物之共熔點組成。此外利用示差掃描熱量計量測出之實驗數據,以Wilson equation回歸與modified UNIFAC model預測之結果相比較,可以得到Wilson equation與modified UNIFAC model皆有滿意之計算結果。
Solid-liquid equilibria of the following three systems have been measured using Differential Scanning Calorimetry ( DSC ) at 101.32 kPa : N-phenylacetamide + 4-aminoacetophenone (1), N-phenylacetamide + 3-hydroxyacetophenone (2), and N-phenylacetamide + 4-hydroxy- acetophenone (3). For all systems simple eutectic behaviors is observed. The experimental data were compared with the results calculated from the Wilson activity model and the Modified UNIFAC ( Dortmund ) model. Good agreements between the experimental data and the calculated results are obtained. The Gray’s model and the eutectic fraction method were also employed to determine the eutectic compositions. The calculated results are also satisfactory compared to the experimental data.
