Didecyldimethylammonium chloride (0.03 mol) was dissolved in 40 mL distilled water and diclofenac sodium salt (0.04 mol) was added to the solution. The solution was stirred at room temperature for 30 min. Chloroform (40 mL) was added to the reaction mixture and the mixture was stirred. After separation of the phases, the organic phase was washed with 40 mL distilled, cold water until chloride ions were no longer detected using AgNO3. Chloroform was removed and the residue was dried at 50° C. in vacuum. The product, didecyldimethylammonium 2-[(2,6-dichlorophenyl)amino]benzeneacetate (100% yield), was obtained as a grease that is soluble in chloroform, acetone, and DMSO. The product lacks miscibility with water and hexane. Thermogravimetric analysis: Tonset5%=162° C., and Tonset=183° C. 1H and 13C NMR (DMSO) were obtained.
