Abstract Densities, speeds of sound, and viscosities at various temperatures were determined for the systems: 2-methylcyclohexanone (2-MCYH) + formamide (F), N-methylformamide (NMF) and N, N-dimethylformamide (DMF). From the experimental results, Excess molar volume VmE, Excess isentropic compressibility κsE, deviation in viscosity Δη and excess Gibbs energy of activation of viscous flow G*E, Excess partial molar properties at infinite dilution V ¯ m, 1 ° E , V ¯ m, 2 ° E , K ¯ s,m, 1 ° E and K ¯ s,m, 2 ° E were calculated. There is evidence of complex formation between unlike molecules. FT-IR properties have been carried out to study the specific interaction, such as the formation of the hydrogen bond between unlike molecules in the binary liquid mixtures, a good agreement is observed among the excess parameters and FT-IR spectroscopic properties.

2-甲基环己酮与酰胺的二元液体混合物的声学、体积和 FTIR 研究

摘要 测定了以下系统的密度、声速和粘度：2-甲基环己酮 (2-MCYH) + 甲酰胺 (F)、N-甲基甲酰胺 (NMF) 和 N, N-二甲基甲酰胺 (DMF)。从实验结果可以看出，摩尔体积过大 VmE、等熵压缩系数过大 κsE、粘度偏差 Δn 和粘性流动的额外吉布斯活化能 G*E、无限稀释下的过分摩尔性质 V¯m、1°E、V¯m , 2 ° E , K¯s,m, 1 °E 和 K¯s,m, 2 °E 被计算出来。有证据表明不同分子之间形成复合物。FT-IR 特性已用于研究特定的相互作用，例如在二元液体混合物中不同分子之间形成氢键，在过量参数和 FT-IR 光谱特性之间观察到良好的一致性。
