Densities (ρ) and speed of sound (u) of binary liquid mixtures of Ricinoleic acid with some halobenzenes at 303.15, 308.15 and 313.15 K and atmospheric pressure have been reported over the entire composition range. From the experimentally measured density (ρ), excess molar volumes (V
), have been calculated. Deviation of the speeds of sound (
u), isentropic compressibility (ks), deviation in isentropic compressibility (ks), deviation in acoustic impedance (z) and intermolecular free length (Lf) have been calculated using experimentally measured speed of sound,(u). Various theoretical speeds of sound and average deviations have been calculated using well established equations like Nomoto (Unmt) Ideal Mixing Rule (Uimr), Junji (Ujunji) and Jacobson’s Free Length Theory, (Uflt). To derive fitting coefficients, (Ai) with standard deviation, (σ), excess properties have been fitted with the Redlich-Kister type polynomial equation. The variation of these properties with composition and temperature has been discussed in terms of molecular interaction on mixing and their interacting abilities. Observations reveal that there have been strong interactions between components. Strength of interactions between components has been described with theoretical computational calculations.

蓖麻油酸与某些卤代苯的二元混合物中分子相互作用的体积，声学和计算研究
在整个组成范围内，已报道了蓖麻油酸与一些卤代苯的二元液体混合物在303.15、308.15和313.15 K的密度（ρ）和声速（u）和大气压。根据实验测得的密度（ρ），已计算出过量的摩尔体积（V ）。声速的偏差（u），等熵可压缩性（k s），等熵可压缩性（k s）偏差，声阻抗（z）和分子间自由长度（L f ）的偏差是通过实验测得的声速来计算的（û）。声音的各种理论速度和平均偏差已使用完善的方程式进行计算，例如Nomoto（U nmt）理想混合规则（U imr），Junji（U junji）和Jacobson的自由长度理论（U flt）。为了获得拟合系数（A i）和标准偏差（σ），多余的性质已与Redlich-Kister型多项式方程式拟合。这些性质随组成和温度的变化已根据混合时的分子相互作用及其相互作用能力进行了讨论。观察表明，组件之间存在强大的交互作用。组件之间相互作用的强度已通过理论计算计算进行了描述。
