摘要:	本研究有三組二元成分混和溶劑系統(正庚烷 + 正癸烷、正庚烷 + 正十二烷、正癸烷 + 正十二烷)以及一組三元成分混和溶劑系統(正庚烷 + 正癸烷 + 正十二烷)，在不同莫耳分率下，溫度在293.15 K 、 298.15 K 、 303.15 K 與308.15 K 四種溫度及壓力在0.1 MPa 下進行密度及黏度的量測。利用密度及黏度之實驗數據計算過剩莫耳體積、黏度偏差及運動黏度。並針對許多專家學者所提出各種對二元系統與三元系統過剩莫耳體積、黏度偏差、黏度與動黏度之模型進行回歸分析，除了可比較各種模型之差異外，最主要可提供這三種烷類混合物密度與黏度之數據做相關的應用。二元成份利用 Redlich-Kister 多項式模型進行回歸過剩莫耳體積及黏度偏差，另外也用Grunberg−Nissan 、 Heric 、 McAllister(three-body) 以及 McAllister(four-body) 半經驗方程式模型來針對黏度進行估算；三元成分在過剩莫耳體積以及黏度偏差上利用 Cibulka 、 Singh 、 Nagata-Sakura 多項式模型進行回歸，並利用 Radojkovic 、 Rastogi 、 Kohler 、 Toop 、 Tsao-Smith 、 Jacob-Fitzner 、 Colinet 、 Scatchard 經驗方程式模型來做預測，另外也用Nissan−Grunberg半經驗方程式模型來針對黏度進行估算。其結果顯示混合物在過剩莫耳體積、黏度偏差以及運動黏度中，實驗所量測的數據與模式計算之結果相當一致。 This study revealed that the density and the viscosity of the binary mixtures of solvent system (n-Heptane + n-Decane, n-Heptane + n-Dodecane, and n-Decane + n-Dodecane) and of the ternary mixtures of solvent system (n-Heptane + n-Decane + n-Dodeacne) 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.
