Benzenesulfinic Acid Sodium Salt Cas 873-55-2
Benzenesulfinic Acid Sodium Salt colorless flake crystal. Dissolve in water. The preparation method is to reduce benzene sulfonyl chloride, sodium metabisulfite, water and sodium hydroxide to sodium benzene sulfinate at pH=3.5 ~ 8.5, 50℃, through decolorization, filtration, cooling Chemicalbook to 15℃, separation of sodium bisulfate, 30% hydrochloric acid at 15 ~ 20℃ acid to benzene sulfinic acid, water washing, and then add alkali to neutralize into salt. Sodium benzenesulfonate is a colorless flake crystal.
