| 摘要: | 本研究中對於(正己烷+正癸烷)、(正己烷+正十二烷)、(正癸烷+正十二烷)、(正庚烷+正壬烷)、(正庚烷+正十二烷)、(正壬烷+正十二烷)，六組二元成分系統及兩組三元成分系統(正己烷+正癸烷+正十二烷)、(正庚烷+正壬烷+正十二烷)在 293.15K、298.15K、303.15K與308.15K四種溫度及常壓下進行密度與黏度之量測。利用量測之實驗數據進行各種相關模型的迴歸分析。不論是二元或三元成分系統均對過剩莫爾體積、黏度偏差、黏度等重要的物理性質進行探討。二元成分系統以 Redlich-Kister 方程式式進行回歸過剩莫爾體積及黏度偏差，另外也用 Grunberg-Nissan 、Heric 以及 McAllister 等半經驗方程式去針對黏度進行計算；三元成分系統於過剩莫爾體積與黏度偏差上利用 Cibulka 、 Singh 、 Nagata-Sakura 方程式進行回歸，並以 Radojkovic 、 Rastogi 、 Kohler 、 Toop 、 Tsao-Smith 、 Jacob-Fitzner 、 Colinet 、 Scatchard 等8種經驗方程式來進行預算，而上述之回歸方程式參數於後續章節中皆有做記載。其結果顯示混合物在過剩莫爾體積、黏度偏差及黏度上所量測之數值與回歸方程式所計算結果相當一致。
This study revealed that the density and the viscosity of the binary mixtures of solvent system (n-Hexane + n-Decane, n-Hexane + n-Dodecane, n-Decane + n-Dodecane, n-Heptane+ n-Nonane, n-Heptane + n-Dodecane, and n-Heptane+ n-Dodecane) and of the ternary mixtures of solvent system (n-Hexane + n-Decane + n-Dodecane, and n-Heptane+ n-Nonane + n-Dodecane) were measured at different mass molar rate, at four temperature conditions (293.15 K, 298.15 K, 303.15 K, and 308.15 K),and at atmospheric pressure. Used the experimental data of the density and of the viscosity to calculate the excess molar volumes, viscosity deviations, and kinematic viscosity, we used the models that proposed by experts and scholars to do the regression analysis. Not only can compare with the differences of each model, but also, importantly, can provide the density and the viscosity of these three alkanes mixtures to do related applications. In the binary mixtures of solvent system, we used the Redlich−Kister polynomial equation to analyze the data of the excess molar volumes and viscosity deviations, used Grunberg−Nissan and Heric correlation equation to analyze the data of the viscosity, and used McAlliater three body and McAllister four body correlation equation to analyze the data of the kinematic viscosity. In the ternary mixtures of solvent system, we used Cibulka, Singh, and Nagata-Sakura, polynomial equation to analyze the data of the excess molar volumes and viscosity deviations, and used Radojkovic, Rastogi, Kohler, Toop, Tsao-Smith, Jacob-Fitzner, Colinet, and Scatchard correlation equation to analyze the data of the excess molar volumes and viscosity deviations, and we also used Nissan−Grunberg correlation equation to analyze the data of viscosity.
These experimental results revealed that the results of the experiment of the excess molar volumes, of the viscosity deviation, of the viscosity, and of the kinematic viscosity were almost as same as the results of models calculation. |
