摘要

使用Ostwald粘度计和比重瓶在T=303.15K下对苯胺+甲苯、苯胺+邻二甲苯和苯胺+均三甲苯的三种二元液体混合物的粘度和密度进行了实验测量。还使用经验关系式计算了粘度，即Bingham关系式、Kendall-Munroe关系式、Arrhenius-Eyring关系式，克罗关系和甘比尔关系。通过计算值和实验值之间的偏差，验证了这些相关性的有效性。这些结果表明，在T=303.15K时，三种二元混合物都存在正偏差。所有关系式的结果与实验结果比较一致。这些用于绘制各个二元液体混合物的组分之间的分子缔合的特征。

Estimation of Viscosities and Their Deviations in Organic Liquid Mixtures at 303.15 K-A Comparative Study

Viscosities and densities are measured experimentally for three binary liquid mixtures of Aniline + Toluene, Aniline + o-Xylene and Aniline + Mesitylene using Ostwald’s viscometer and Specific gravity bottle at T = 303.15 K. Viscosities have also been calculated using empirical relations viz., Bingham relation, Kendall-Munroe relation, Arrhenius -Eyring relation, Croenaurer-Rothfus-Kermore relation and Gambrill relation. The validity of these correlations has been verified by respective deviations between calculated values and experimental values. These results show that positive deviations are present in all the three binary mixtures at T = 303.15 K. The results of all the relations are comparatively in good agreement with experimental results. These are used to draw the characteristics of the molecular association among the components of respective binary liquid mixtures.
