YieldReaction ConditionsOperation in experiment
With hydrogenchloride; calcium carbonate; In ice-water; water; EXAMPLE 94 730 ml of water and 159 g of Na2 SO3 (95percent strength by weight) were introduced first. 530 g of 4-acetylaminobenzenesulfonyl chloride were then added a little at a time with stirring at 70° C., while the pH was maintained at about 9 with 95 ml of 50percent strength by weight sodium hydroxide solution. After 3 hours of subsequent stirring at 70° C., insolubles were filtered off, 250 g of ice were added at 30° C., and 375 ml of 17percent strength by weight hydrochloric acid were added with stirring at pH 1.0 to bring down a precipitate, while the temperature was maintained at <=10° C. The resulting suspension was filtered with suction after 1.5 hours and the filter residue was washed with 1.5 1 of ice-water. The filter material was then suspended in 400 ml of ice-water and dissolved at about 15° C. with 74 ml of 30percent strength by weight sodium hydroxide solution at pH 9.0. This gave 782 ml of a clear solution containing 185 g of the sodium salt of 4-acetylaminobenzenesulfinic acid. 654 ml of this solution (corresponding to 154.7 g of the sodium salt of 4-acetylaminobenzenesulfinic acid) were introduced first, and 365 g of 50percent strength by weight 2-nitrochlorobenzene-4-sulfonic acid were added with stirring at pH 6.2. The pH was then adjusted to 7.0 with a few drops of sodium hydroxide solution. 9 g of CaCO3 and 0.35 g of copper powder were added, and the mixture was stirred at 100° C. for 20 hours and then filtered hot. The resulting solution was admixed with 180 ml of 17percent strength by weight hydrochloric acid and refluxed for 4 hours. The suspension obtained was then filtered with suction at room temperature, and the filter residue was washed with 2 1 of ice-water and dried at 70° C. under reduced pressure. Yield: 250 g of 4-amino-2'-nitro-4'-sulfodiphenyl sulfone of the formula STR179
