YieldReaction ConditionsOperation in experiment
9.5%. With sulfuric acid; sulfur trioxide; In water; A reaction vessel was charged with 62.8 grams (34 ml.) of concentrated sulfuric acid and 37.2 grams (19.3 ml.) of 30 percent oleum to form 100 grams of 100 percent sulfuric acid. To this 44.6 grams (0.2 mole) of 2-amino-1-naphthalenesulfonic acid was added to form a mixture. After heating the mixture to 60C., 32.0 grams (0.4 mole) of liquid sulfur trioxide was added dropwise over a period of 35 minutes with the temperature being gradually raised to 100C. The reaction mixture was held at 100C. for 6 hours and cooled to room temperature. The cooled reaction mixture was diluted with 170 ml. of water and further cooled to 20C. Thereafter, the mixture was refluxed for 3 hours and the precipitate which formed was separated by filtration. The overall yield of 2-amino-6,8-naphthalenedisulfonic acid was 9.5 percent. The overall yield of 2-amino-5,7-naphthalenedisulfonic acid was 46 percent.
