Abstract In this work we have developed an equation for correlating the kinematic viscosities of binary mixtures of ionic liquids with organic solvents and with water in a wide range of temperature at atmospheric pressure. The new correlation uses the molecular surface fraction as composition variable. The performance of the new equation to correlate the viscosity has been tested using 5746 literature viscosity data of 111 binary mixtures. We have also compared the performance of the new equation with recently developed equations for the kinematic viscosity such as the Nava-Rios, Eyring Modified Two Suffix Margules, Fang-He and Eyring-Wilson equations. The new equation correlates the kinematic viscosity with an average absolute percentage of deviation of 2.64% for binary mixtures of ionic liquids + water and 1.44% for binary mixtures of ionic liquids + organic compounds.

离子液体与有机溶剂和水的二元混合物粘度的相关性

摘要 在这项工作中，我们开发了一个方程，用于将离子液体与有机溶剂和水的二元混合物在大气压下的广泛温度范围内的运动粘度相关联。新的相关性使用分子表面分数作为组成变量。已使用 111 种二元混合物的 5746 篇文献粘度数据测试了与粘度相关联的新方程的性能。我们还将新方程的性能与最近开发的运动粘度方程进行了比较，例如 Nava-Rios、Eyring 修正的两个后缀 Margules、Fang-He 和 Eyring-Wilson 方程。对于离子液体 + 水和 1 的二元混合物，新方程将运动粘度与平均绝对偏差百分比 2.64% 相关联。
