m-aminobenzenesulfonic - Preparation Method
Open Data Verified Data
The sulfonation reaction was carried out by nitrobenzene and fuming sulfuric acid, the reaction product was neutralized to Neutral with liquid alkali, and the M-nitrobenzenesulfonic acid sodium salt solution was obtained by filtration. The solution was reduced to M-aminobenzenesulfonate by using iron chips as a catalyst, and the iron sludge was removed by filtration. The filtrate was the M-aminobenzenesulfonate sodium salt solution. Sulfuric acid was added to the acid-decanting pot until the Congo red paper turned blue and the temperature was maintained at 70 °c. Then centrifugal filtration is the m-aminobenzenesulfonic acid sodium slurry.
