반응 단계

25 g of benzenesulfonic acid hydrazide, 200 ml of water, 20 ml of 10 N hydrochloric acid, and 1.25 g of a condensation product of stearic acid with taurine were stirred for 30 minutes. After 60 g of ice were added, 34 ml of an aqueous sodium nitrite solution having a content of 30 g of sodium nitrite per 100 ml of solution were added dropwise over a period of about 30 minutes. The mixture was stirred for 30 minutes while an excess of nitrite was maintained. The excess nitrite was destroyed with a small amount of amidosulfonic acid and the mixture was neutralized with about 5 ml of 10 N sodium hydroxide solution. An emulsion of benzenesulfonic acid azide was obtained.
