| 摘要: | 本研究針對鄰二氯苯、氯苯、正己烷之二元成份混合溶劑系統的密度和黏度，在293.15K、298.15K、303.15K、308.15K等四種溫度以及常壓下進行量測。量測密度使用震盪管密度計 (由奧地利Anton Paar生產製造，型號為DMA5000)，黏度量測使用落球式黏度計(由Anton Paar生產製造，型號為Lovis 2000ME)。利用量測的實驗數據進行計算過剩莫爾體積以及黏度偏差。利用Redlich−Kister多項式進行回歸過剩莫爾體積及黏度偏差兩個偏離量，另外也用半實驗式Grunberg−Nissan、Heric以及McAllister方程式來針對黏度進行估算，上述所有回歸方程式的參數在文章中皆有提出。其結果顯示混合物在過剩莫爾體積、黏度偏差以及黏度中，實驗所量測的數據與模式計算之結果相當一致。
Density and viscosity of binary mixtures of 1,2-dichlorobenzene , chloroform , n-hexane , was measured at (298.15, 303.15, 308.15, and 318.15) and at normal atmospheric pressure over the entire composition. Densities and viscosities were determined using density meter (DMA 5000M, Anton Paar) and rolling-ball viscometer (Lovis 2000ME, Anton Paar), respectively. From the experimental data, the excess molar volumes and viscosity deviations were calculated. The excess molar volumes and viscosity deviations for the binary mixture were fitted to the Redlich−Kister polynomial equation. The viscosity results have been fitted by Grunberg−Nissan, Heric, and McAllister correlation equation. The model parameters for the binary are also reported. The agreement between calculated and experimental data for excess molar volumes, viscosity deviations and viscosities was rather good. |
