Background: The non-covalent molecular interactions of 1-Ethyl-3- methylimidazolium chloride-aluminum chloride and pure alcohols are attracting attention in the industry, academic and research. Chemists, engineers, designers, and some researchers are interested in accessing trustworthy databases.

Objective: 1-Ethyl-3-methylimidazolium chloride-aluminum chloride interacts with pure alcohols with non-covalent interactions. Physicochemical properties with their convincing data interpret the interactions occurring there.

Methods: For that limiting apparent molar volume, molar refraction, and limiting apparent molar isentropic compressibility of the binary systems viz., {([EMIm]Cl/AlCl3) +methanol}, {([EMIm]Cl/AlCl3) +ethanol}, {([EMIm]Cl/AlCl3) +1-propanol}, and {([EMIm]Cl/AlCl3)+ 1-butanol} have been calculated using physicochemical properties i.e.,. density, refractive index, and speed of sound, respectively within the temperature range T=293.15K-318.15K (with the interval of 5K).

Results: The ionic liquid strongly interacts with 1-butanol (106⋅φov =874.52 m3 mol-1, 106·RM = 211.13 m3 mol-1, and 10-11·φok= -0.10 m3 mol-1 Pa-1, 108· (∂φoE/∂T)P = 1.52 m3 mol-1 K-2) than other chosen primary alcohol at a higher temperature (318.15K). Among the individual ions, the 106·φov(ion) is higher for ALCI4-(522.96 m3 mol-1) than [EMIm]+ (351.56 m3 mol-1) at high temperature (318.15K) in 1-butanol.

Conclusion: The molecular interactions occurring between the ionic liquid and solvent molecules are due to the structure-making capacity caused by intermolecular forces and non-covalent interactions. Where the 1-butanol strongly interacts with ionic liquids. In between the ions, the anaion interaction is greater than cation to solvents.
