Abstract Surface tension of various binary mixtures has been evaluated over the past years since the results add great contribution to many engineering applications. The binary systems {nonane + toluene, nonane + benzene, nonane + cyclooctane, hexadecane + toluene, hexadecane + benzene, hexadecane + cyclooctane}26 were studied since no literature data were conveyed based on our best review. Therefore, surface tension (σ) and density (ρ) of these binary systems were appraised at different temperatures of 298.2 K, 303.2 K, 308.2 K and 313.2 K at atmospheric pressure, and various mole fractions. Du Nouy Ring Device was applied experimentally to determine the surface tension of these organic mixtures. The outcomes were analyzed with the existing theoretical values attained from Brock-Bird correlation and Goldsack-Sarvas method and the average absolute relative deviations (AAD %) were obtained as 10.26% and 3.75%, respectively. In this work we have shown the success of our recent proposed model for correlating the surface tension of the studied binary organic mixtures with an overall average absolute relative deviation of 3.00%.

基于新的无量纲数的二元有机混合物的表面张力

摘要 在过去的几年里，人们对各种二元混合物的表面张力进行了评估，因为这些结果为许多工程应用做出了巨大贡献。研究了二元系统 {壬烷 + 甲苯、壬烷 + 苯、壬烷 + 环辛烷、十六烷 + 甲苯、十六烷 + 苯、十六烷 + 环辛烷}26，因为根据我们的最佳评论没有传达任何文献数据。因此，这些二元系统的表面张力 (σ) 和密度 (ρ) 在大气压下的 298.2 K、303.2 K、308.2 K 和 313.2 K 的不同温度和各种摩尔分数下进行了评估。Du Nouy 环装置通过实验来确定这些有机混合物的表面张力。使用 Brock-Bird 相关和 Goldsack-Sarvas 方法获得的现有理论值分析结果，平均绝对相对偏差 (AAD %) 分别为 10.26% 和 3.75%。在这项工作中，我们展示了我们最近提出的模型的成功，该模型将研究的二元有机混合物的表面张力与 3.00% 的总体平均绝对相对偏差相关联。
