The current investigation delves into a comparative evaluation of the thermophysical behavior observed in 2-methyl-1-pentanol and short-chain alcohols (C₄-C₇), from 1-butanol to 1-heptanol over a temperature range of 293.15 to 333.15 K. The primary emphasis of this research centers on analyzing the excess molar volumes and viscosity deviations of these compounds. The findings indicate positive excess molar volumes in the mixtures, which escalate with the elongation of the alkyl chain in the alcohols. Viscosity measurements exhibit deviations from ideal behavior, showing a negative trend that intensifies with longer alkyl chains, indicative of weak molecular interactions between 2-methyl-1-pentanol and the alcohols. Additionally, the study employs the Cubic-Plus-Association (CPA) model to establish correlations among the densities of these mixtures. Remarkably, the model closely aligns with experimental findings, demonstrating a maximum disparity of only 0.57% in the 2-methyl-1-pentanol + 1-pentanol mixture.

当前的研究深入研究了在 293.15 至 333.15 的温度范围内，对 2-甲基-1-戊醇和短链醇 (C ₄ -C ₇ )（从 1-丁醇到 1-庚醇）中观察到的热物理行为进行了比较评估。 K. 这项研究的主要重点是分析这些化合物的过量摩尔体积和粘度偏差。研究结果表明混合物中存在正过量摩尔体积，并且随着醇中烷基链的伸长而增加。粘度测量显示出与理想行为的偏差，显示出随着烷基链越长而加剧的负趋势，表明 2-甲基-1-戊醇和醇之间的分子相互作用较弱。此外，该研究还采用三次加关联 (CPA) 模型来建立这些混合物密度之间的相关性。值得注意的是，该模型与实验结果非常吻合，表明 2-甲基-1-戊醇 + 1-戊醇混合物中的最大差异仅为 0.57%。
