• 中文摘要： 本研究以Patel-Teja狀態方程式替代活性係數模式,對多種類型之雙成分系統行固液相平衡計算。研究指出當交互作用參數, k/sub aij/,被視為一常數時,對於非極性系統之固體溶解度計算,可獲得令人滿意的結果; 然而對於極性系統,則需要將k/sub aij/視為溫度相依。此外,該狀態方程式若採用兩個隨溫度而異之交互作用參數,k/sub aij/與k/sub bij/,可準確地計算出高壓下固體溶解度之等溫線。
• 英文摘要： The Patel-Teja equation of state, rather than an activity coefficient model, was applied in this present study towards solid-liquid equilibrium calculation for a variety of binary systems. With a constant cross parameter of k/sub aij/, the equation yielded satisfactory results for the solid solubility of nonpolar systems, whereas a temperature dependent k/sub aij/ appeared as being necessary for the polar systems. Moreover, the equation of state with two temperature-specific cross parameters of k/sub aij/ and k/sub bij/ accurately reproduced the isotherms of the solid solubilities at elevated pressures.
