Abstract
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.
