Abstract

The densities (ρ), speeds of sound (u), and viscosities (η) are reported for binary mixtures of propiophenone with ortho-substituted aniline (2-chloroaniline, 2-methylaniline, and 2-methoxyaniline) over the entire composition range from 303.15 to 318.15 K and at atmospheric pressure 0.1 MPa. The excess/deviation functions (V^E, \(k_{s}^{E}\), and Δη) are calculated from the measured densities, speeds of sound and viscosities at experimental temperatures. The excess properties have been analyzed through molecular interactions. The FT-IR data indicate that the formation of intermolecular hydrogen bonding (N–H⋅⋅⋅O–H) between hydrogen atom of amine group of o-substituted aniline and oxygen atom of carbonyl of propiophenone in the binary liquid mixtures.

伴随溶液的研究：丙苯酮和邻位取代苯胺的二元液体混合物的热力学参数

摘要

报告了在整个组成范围内，苯丙酮与邻位取代苯胺（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），声速（u）和粘度（η）。 303.15至318.15 K，在大气压下为0.1 MPa。过量/偏差函数（V ^E，\（k_ {s} ^ {E} \）和Δη）是根据在实验温度下测得的密度，声音速度和粘度计算得出的。通过分子相互作用分析了多余的性质。FT-IR数据表明，o的胺基氢原子之间形成了分子间氢键（N–H⋅⋅⋅O–H）二元液体混合物中苯乙酮和苯丙酮羰基的氧原子被取代。
