Dimethylformamide → Sodium 2-(dodecanoyloxy)benzene-1-sulfonate

Participants

Reaction Steps

One-hundred grams of sodium p-phenolsulfonate which was previously dehydrated was dispersed in 300 g of dimethylformamide (hereinafter simply referred to as "DMF"), and lauroyl chloride at 50° C. was added dropwise to the above mixture over a period of 30 minutes while stirring with a magnetic stirrer. After completing the dropwise addition, the components were allowed to react with one another for 3 hours. Thereafter, the DMF was distilled off at 100° C. under a reduced pressure of 0.5 to 1 mmHg. After rinsing the resulting mixture with acetone, recrystallization was carried out in a water/acetone solvent (molar ratio 1:1), to give sodium lauroyloxybenzenesulfonate (yield 85%).
