چکیده

This research paper refers to the study of the thermodynamic and transport properties of 3-methyl-2-butanol and normal alcohols ranging from C3– C6 (1-propanol to 1-hexanol), focusing particularly on the density and viscosity of these mixtures within a temperature range of 293.15–323.15 K. Findings indicate binary mixtures show negative excess molar volumes, which gradually become less negative with an increase in the alkyl chain length of the alcohols. In terms of viscosity, all mixtures consistently demonstrated negative deviations, becoming more negative as the alkyl chain extended. These results underscore a strong molecular interaction occurring between 3-methyl-2-butanol and short-range 1-alkanol. Additionally, the research incorporated the Cubic-Plus-Association (CPA) model to correlate the densities of binary mixtures. The model aligned well with the experimental densities, proving its effectiveness in correlating the density trends of these mixtures. The maximum difference noted between the experimental results and the CPA model’s correlated values was in the 3-methyl-2-butanol and 1-hexanol mixture, with a slight discrepancy of only 0.41%. This small variance further highlights the CPA model’s accuracy in mirroring experimental findings.
