YieldReaction ConditionsOperation in experiment
With hydrogenchloride; sodium hydroxide; calcium chloride; sodium nitrite; In water; EXAMPLE 1 A solution of 24.2 grams (0.1294 mole) of pure 6-amino-m-toluenesulfonic acid and 1.2 grams (0.0054 mole) of 2-naphthylamine-1-sulfonic acid is prepared in 500 ml of water by adding 57 ml of a 10% solution of sodium hydroxide and adjusting the pH to 11.5. A solution of 35.6 grams of calcium chloride and 1.5 grams of strontium nitrate in 100 ml of water is added thereto and the mixture cooled to 0 C. with ice. The amines are diazotized by adding 35 ml (0.14 mole) of 4 N sodium nitrite, followed by 150 ml (0.411 mole) of 10% hydrochloric acid. The mixture is stirred for about 3 minutes at 0 C., while maintaining excess nitrous acid. 2-Hydroxy-3-naphthoic acid (28.0 grams, 0.1489 mole) is dissolved in 500 ml of water by adding 180 ml of 10% sodium hydroxide.
