Densities, ρ, viscosities, η, and ultrasonic sound velocities u of pure methyl isobutylketone, diethylketone, cyclopentanone, cyclohexanone, 2-methyl cyclohexanone and those of their binary mixtures with N-methyl aniline were measured at 303.15 K over the entire composition range. These experimental data have been used to calculate the excess volume (VE), deviation in ultrasonic sound velocity (∆u), isentropic compressibility (κs), intermolecular free length (Lf), excess intermolecular free length ($$ L_{\text{f}}^{\text{E}} $$LfE), acoustic impedance (Z), excess isentropic compressibility ($$ \kappa_S^{\text{E}} $$κSE), deviation in viscosity (∆η) and excess Gibbs energy of activation of viscous flow (G*E). The viscosity data have been correlated using three equations proposed by Grunberg and Nissan, Katti and Chaudhri, and Hind et al. The excess/deviations have been fitted by Redlich–Kister equation and the results are discussed in terms of molecular interactions present in these mixtures.

N-甲基苯胺与甲基异丁基酮、+3-戊酮和+环烷酮在 303.15 K 的二元混合物中分子相互作用的超声研究

纯甲基异丁基酮、二乙基酮、环戊酮、环己酮、2-甲基环己酮及其与 N-甲基苯胺的二元混合物的密度、ρ、粘度、η 和超声波速度 u 在整个组成范围内在 303.15 K 下测量。这些实验数据已被用于计算多余体积 (VE)、超声波声速偏差 (Δu)、等熵压缩率 (κs)、分子间自由长度 (Lf)、分子间自由长度 ($$ L_{\text{ f}}^{\text{E}} $$LfE)、声阻抗 (Z)、超等熵压缩率 ($$ \kappa_S^{\text{E}} $$κSE)、粘度偏差 (Δη)粘性流激活的过量吉布斯能 (G*E)。粘度数据已使用 Grunberg 和 Nissan、Katti 和 Chaudhri 以及 Hind 等人提出的三个方程相关联。
