Densities (ρ), speeds of sound (u), and viscosities (η) are reported for binary mixtures of 2-methoxyaniline with chlorinated ethane components (1,2-dichloroethane, 1,1,2-trichloroethane and 1,1,2,2-tetrachloroethane) over the entire composition range of mole fraction at T = (303.15–313.15) K and at atmospheric pressure (0.1 MPa). The excess properties: excess molar volume, excess isentropic compressibility and deviation in viscosity are calculated from the experimental density, speed of sound and viscosity. Excess properties are correlated using the Redlich–Kister polynomial equation. The excess partial molar volumes and excess partial molar isentropic compressibilities are calculated for all the binary systems throughout the composition range and at infinite dilutions. The results are analyzed in terms of electron donor–acceptor interactions leading to the formation of intermolecular complexes and hydrogen bonding between 2-methoxyaniline and chlorinated ethane molecules. The VE results are analyzed in light of the Prigogine–Flory–Patterson theory. Analysis of each of the three contributions viz. interactional, free volume and P* to VE has shown that the interactional contribution are positive for all studied systems, the free volume and P* contributions are negative for all the binary mixtures.

2-甲氧基苯胺与氯化乙烷二元混合物在不同温度下的分子间相互作用研究

报告了 2-甲氧基苯胺与氯化乙烷组分（1,2-二氯乙烷、1,1,2-三氯乙烷和 1,1,2 ,2-四氯乙烷）在 T = (303.15–313.15) K 和大气压 (0.1 MPa) 下的整个摩尔分数组成范围内。多余的性质：多余的摩尔体积、多余的等熵压缩性和粘度偏差是根据实验密度、声速和粘度计算得出的。使用 Redlich-Kister 多项式方程关联多余的属性。在整个组成范围和无限稀释下，计算所有二元系统的过量部分摩尔体积和过量部分摩尔等熵压缩率。结果根据电子供体-受体相互作用进行分析，导致形成分子间复合物和 2-甲氧基苯胺和氯化乙烷分子之间的氢键。根据 Prigogine-Flory-Patterson 理论分析 VE 结果。分析三个贡献中的每一个，即。相互作用、自由体积和 P* 对 VE 的研究表明，所有研究系统的相互作用贡献都是正的，所有二元混合物的自由体积和 P* 贡献都是负的。
