Abstract The activation parameters of viscous flow can be used to probe the molecular interactions in fluids from viscosity experimental data. They are assessed by mathematical derivations of the Eyring equation, but differences in these derivations can generate parameters that lead to conflicting interpretations. In this work, a new method for the estimation of the activation parameters of viscous flow is proposed and compared with two other methods previously reported in the literature. It is shown that the new method is the only presenting theoretically consistent trends, as confirmed by its application to alkanes and ionic liquids.

通过 Eyring 方程计算粘性活化参数的理论一致性及其解释

摘要 粘性流动的激活参数可用于从粘性实验数据中探测流体中的分子相互作用。它们通过 Eyring 方程的数学推导进行评估，但这些推导的差异可能会产生导致解释相互矛盾的参数。在这项工作中，提出了一种估计粘性流激活参数的新方法，并与之前文献中报道的其他两种方法进行了比较。结果表明，新方法是唯一呈现出理论上一致的趋势，正如其在烷烃和离子液体中的应用所证实的那样。
