Abstract
In this work, we synthesized three distinct types of asymmetrical dicationic ionic liquids: 1- (2- (1- decyl -1H -imidazolium-3 -yl) ethyl) pyridinium bromide (IL301), 1- (5- (1- decyl -1H-imidazolium-3-yl) pentyl) pyridinium bromide (IL302), and 1-(10- (1- decyl -1H-imidazolium-3-yl) decyl) pyridinium bromide (IL303). Their structures were characterized by using the conventional techniques of analysis, (elemental analysis, Fourier Transform infrared spectroscopy, and proton nuclear magnetic resonance). The surface characteristics of the synthesized asymmetrical dicationic ionic liquids, (surface tension, critical micelle concentration, effectiveness, maximum surface excess, and minimum surface area) were studied. Additionally, the standard free energies of micellization and adsorption were calculated for each compound. The efficiency of IL301, IL302, and IL303 to enhance base oil was examined and recorded, specifically in terms of oxidation stability (measured through changes in total acid number [TAN] and viscosity) and foam characteristics. The data indicated that IL303 was the most effective base oil enhancer, followed by IL302 and IL301.
