Density (ρ), ultrasonic velocity (u), adiabatic compressibility (β), apparent molar volume (Ø), acoustic impedance (Z), intermolecular free length (L(f)), relative association (RA) of binary mixtures of 2'-chloro-4-methoxy-3-nitro benzil (abbreviated as 2CBe) in ethanol, acetonitrile, chloroform, dioxane and benzene were measured at different concentrations at 298 K. Several useful parameters such as excess density, excess ultrasonic velocity, excess adiabatic compressibility, excess apparent molar volume, excess acoustic impedance and excess intermolecular free length have been calculated. These parameters are used to explain the nature of intermolecular interactions taking place in the binary mixture. The above study is useful in understanding the solute--solvent interactions occurring in different concentrations at room temperature.
在 298 K 下，测定了 2'-氯-4-甲氧基-3-硝基苯甲酰（简称 2CBe）在乙醇、乙腈、氯仿、二氧六环和苯中的二元混合物的密度（ρ）、超声速度（u）、绝热压缩率（β）、表观摩尔体积（Ø）、声阻抗（Z）、分子间自由长度（L(f)）和相对缔合（RA）。计算了过量密度、过量超声速度、过量绝热压缩率、过量表观摩尔体积、过量声阻抗和过量分子间自由长度等几个有用参数。这些参数用于解释在二元混合物中发生的分子间相互作用的性质。上述研究有助于理解室温下不同浓度下溶质-溶剂相互作用。
