ABSTRACT

The densities (ρ), viscosities (η), and speeds of sound (u) are reported for binary mixtures of 2-methylcyclohexanone with ortho-substituted anilines (2-chloroaniline, 2-methylaniline and 2-methoxyaniline) over the entire composition range from 303.15 K to 313.15 K and at atmospheric pressure 0.1 MPa. The excess functions and deviation in viscosity were calculated from the densities, speeds of sound, and viscosities at experimental temperatures. FT-IR properties have been carried out and analysed to study the presence of specific interaction such as the formation of hydrogen bonding of the type (O-H·····N or N-H·····O) between unlike molecules in the binary liquid mixtures, a good agreement is observed among the excess parameters and FT-IR properties.

摘要

报告了 2-甲基环己酮与邻位取代苯胺（2-氯苯胺、2-甲基苯胺和 2-甲氧基苯胺）在整个组成范围内的二元混合物的密度 ( ρ )、粘度 ( η ) 和声速 ( u )从 303.15 K 到 313.15 K 和大气压 0.1 MPa。从密度、声速和实验温度下的粘度计算过量函数和粘度偏差。FT-IR 特性已被执行和分析，以研究特定相互作用的存在，例如二元分子中不同分子之间形成类型（OH·····N 或 NH·····O）的氢键。对于液体混合物，在过量参数和 FT-IR 特性之间观察到了很好的一致性。
