Vorschrift

A solution of 0.65 mol of ammonia in 1,050 ml of absolute ethanol is added dropwise, with stirring, to 0.13 mol of 1,2-benzenedisulphonyl chloride in 720 ml of absolute toluene at 25° C. The mixture is stirred a further hour, slight cloudiness is removed by filtration through a layer of kieselguhr, and the filtrate is evaporated to dryness. The ammonium salt of 1,3,2-benzodithiazole 1,1,3,3-tetroxide is obtained.
