Benzenesulfinic Acid Sodium Salt Cas 873-55-2 yog dab tsi?

Benzenesulfinic Acid Sodium Ntsev tsis muaj xim tsis muaj pob zeb siv lead ua. Dissolve hauv dej. Txoj kev npaj yog txo benzene sulfonyl chloride, sodium metabisulfite, dej thiab sodium hydroxide rau sodium benzene sulfinate ntawm pH = 3.5 ~ 8.5, 50 ℃, los ntawm decolorization, pom, txias tshuaj rau 15 ℃, sib cais ntawm sodium bisulfate, 30% hydrochloric acid ntawm 15 ~ 20 ℃ acid rau benzene sulfinic acid, ntxuav dej, thiab ces ntxiv alkali rau neutralize rau ntsev. Sodium benzenesulfonate yog cov xim tsis muaj xim tsis muaj xim.
