N-diazobenzenesulfonamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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. were added dropwise over a period of about 30 minutes was maintained The excess nitrite was destroyed with a small amount of amidosulfonic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 26.3 g of benzenesulphonohydrazide, 100 ml of water, 21 ml of 10N hydrochloric acid and 1.3 g of Emulgator [emulsifier] FD (a fatty alcohol/ethylene oxide addition product) are stirred for 30 minutes, 60 g of ice are added, and a solution of 19.5 g of sodium nitrite in 50 ml of water is then added dropwise in the course of about 30 minutes. The batch is stirred for 30 minutes, excess nitrite is then destroyed with a small amount of sulphamic acid, and excess acid is neutralised with about 5 ml of 10N sodium hydroxide solution. An emulsion of benzenesulphonyl azide is obtained. The batch is stirred for 30 minutes excess nitrite is then destroyed with a small amount of sulphamic acid, and excess acid

The batch is stirred for 30 minutes, an excess of nitrite being maintained. The nitrite excess is then destroyed with a small amount of sulphamic acid, and excess acid is neutralised with about 5 ml of 10N sodium hydroxide solution (pH 4-7). An emulsion of benzenesulphonyl azide is obtained. are then added dropwise in the course of about 30 minutes The nitrite excess is then destroyed with a small amount of sulphamic acid, and excess acid
