PROCEDURE

实验过程

The stoichiometric mixture (0.025 mol) of didecyldimethylammonium chloride and naproxen sodium salt were dissolved in distilled water and stirred at room temperature for 1 h. The product was extracted by ethyl acetate and organic phase was separated and then washed with distilled water. Ethyl acetate phase was removed and solvent evaporated. The product, didecyldimethylammonium (S)-6-methoxy-α-methyl-2-naphthaleneacetate (95% yield), was dried under vacuum. The product is soluble in chloroform, acetone, and DMSO. It lacks miscibility with water and hexane. Thermogravimetric analysis: Tonset5%=156° C., and Tonset=190° C. 1H and 13C NMR (DMSO) were obtained.
