실험 절차
The reaction was performed in an inert atmosphere. N,N-dimethyldecylamine (16.21 mmol, 3.7 g) and 2-methoxyethyl 4-methylbenzenesulfonate (16.21 mmol, 3.71 g) prepared in the previous step were mixed together in a round bottom flask. Dioxane (10 mL) was added to the reaction mixture. The reaction mixture was heated at 75° C. for 18 hours. The solvent was removed by a rotoevaporator, and the remaining viscous liquid was cooled and dried. A white solid was obtained as N-(2-methoxyethyl)-N,N-dimethyldecan-1-aminium 4-methylbenzenesulfonate. The reaction was also performed in absence of any solvent and the desired product was obtained in quantitative yield. Similarly other surfactants were synthesized following the above-mentioned method.
