Abstract
In this work, three asymmetric dicationic ionic liquids, namely, 1-(2-(1-decyl-1H-imidazolium-3-yl)ethyl)-4-methylpyridinium bromide (IL101), 1-(5-(1-decyl-1H-imidazolium-3-yl)pentyl)-4-methylpyridinium bromide (IL102), and 1-(10-(1-decyl-1H-imidazolium-3-yl)decyl)-4-methyl-pyridinium bromide (IL103) were synthesized. Their structures were confirmed and characterized via, elemental analysis, Fourier transform infra-red spectroscopy and proton nuclear magnetic resonance. The surface properties of these ionic liquids, surface tension, critical micelle concentration, effectiveness, maximum surface excess, and minimum surface area, were investigated with different concentrations at 25°C. Standard free energies of micellization and adsorption were obtained. They were studied and tested as base oil improvers, especially oxidation stability, (through studying the change in total acid number [TAN] and viscosity), and foaming characteristics. The efficiency of these compounds as base oil improvers is ranked as follows, IL103 > IL102 > IL101.
