水、低碳醇与环己烷间的液-液平衡的测定与推算
DETERMINATION AND PREDICTION OF LIQUID LIQUID EQUILIBRIA FOR THE SYSTEMS OF WATER-HIGHER ALCOHOLS-CYCLOHEXANE
【摘要】 用浊点法与折光分析相结合的方法测定了水-异丁醇-环己烷三元系(体系Ⅰ)30℃下的液-液平衡相图。用色谱分析方法测定了水-若干低碳醇(体系Ⅱ)及水-低碳醇-环己烷(体系Ⅲ)的液-液平衡关系。用UNIQUAC模型预测,实测值与计算值平均偏差对体系Ⅰ为0.49%(mol,下同),对体系Ⅱ为O.71%。体系Ⅲ为1.07%。
【Abstract】 Liquid Liquid equilibrium(LLE) for the system containing water-isobutanol-cyclohexane(Ⅰ) at 30℃ was determined by cloud point titration and refractive index determination. Chromatography was used for determination of LLE for the systems of water-higher alcohols(Ⅱ) and the systems of water-higher alcohols(ethanol, 1-propanol, isobutanol isoamyl alcohol)-cyclohexane(Ⅲ).The average deviations of values calculated by UNIQUAC model from experimental results were 0.49%(mole) for system Ⅰ, 0.71% for system Ⅱ, and 1.07% for system Ⅲ.
