Investigation on synthesis of two ammonium based ionic liquids from fatty acids and triethylamine

This study focused on preparing the two low cost ILs triethylammonium oleate and triethylammonium stearate from low cost triethylamine and corresponding fatty acids. The long hydrocarbon chains of the carboxylate in ILs make them to stably disperse in the lubricants and increase the effeciency of additives. In addition, carboxylate ions are stable and not hydrolysed in contact with water.
