Abstract

: The parameters like density( ρ ), ultrasonic velocity (U), and viscosity ( η ) were experimentally measured. The excess parameters like adiabatic compressibility, acoustic impedance, free volume, free length, internal pressure and ultrasonic velocity in addition to K value were computed from the experimental data. The variation of these parameters at a constant temperature for the three ternary systems, namely OMP + 1-pentanol+n-hexane, N, N-DMF + 1-pentanol+n-hexane, and MMP + 1-pentanol+n-hexane, have been discussed in the light of molecular interaction. Further, certain theoretical studies are validated with respect to experimental velocities, and the Chi-square test for the goodness of fit is also applied to check the validity of such theoretical models.

313k超声技术对正己烷溶液中1-戊醇与某些有机化合物三元体系的过量性能及理论评价
实验测量了密度(ρ)、超声速度(U)、粘度(η)等参数。根据实验数据计算了除K值外的绝热压缩率、声阻抗、自由体积、自由长度、内压、超声速度等多余参数。本文从分子相互作用的角度讨论了OMP + 1-戊醇+正己烷、N, N- dmf + 1-戊醇+正己烷和MMP + 1-戊醇+正己烷这三个三元体系在恒温下这些参数的变化。进一步,针对实验速度对某些理论研究进行了验证,并采用卡方拟合优度检验来检验这些理论模型的有效性。
