The densities (ρ), viscosities (η) and speeds of sound(u) are reported for binary mixtures of tetrachloromethane with ortho-substituted aniline (2-chloroaniline, 2-methylaniline, and 2-methoxyaniline) over the entire composition range from 298.15 K to 318.15 K and at atmospheric pressure (0.1 MPa). The excess functions and deviation in viscosity are calculated from the densities, speeds of sound and viscosities at experimental temperatures. FT-IR properties have been carried out and analyzed to study the presence of specific interaction such as the formation of hydrogen bonding of the type (N-H·····Cl) between unlike molecules in the binary liquid mixtures. A good agreement is observed among the excess parameters and FT-IR properties.

报告了四氯甲烷与邻位取代苯胺（2-氯苯胺、2-甲基苯胺和 2-甲氧基苯胺）的二元混合物的密度 ( ρ )、粘度 ( η ) 和声速 ( u ) 在 298.15 K 至 318.15 K，在大气压 (0.1 MPa) 下。根据密度、声速和实验温度下的粘度计算超额函数和粘度偏差。FT-IR 特性已被执行和分析，以研究特定相互作用的存在，例如在二元液体混合物中不同分子之间形成 (NH·····Cl) 类型的氢键。在过量参数和 FT-IR 特性之间观察到良好的一致性。
