Chemical: Benzenesulfonic acid, 2,4-diamino-
REACH registered substance: 2,4-diaminobenzenesulphonic acid (EC: 201-846-5)
용도2,4-Diaminobenzenesulfonic acid was used in preparation of series of sulfonated homo- and random co-polyimides.
일반 설명2,4-Diaminobenzenesulfonic acid is an sulfonated aromatic amine and its aerobic biodegradation was reported.
생산 방법2,4-Diaminobenzenesulfonic acid is obtained by sulfonating a solution of m-phenylenediamine in 100% sulfuric acid with oleum at 155 ℃, adding water to the sulfonation mixture, desulfonating the resulting disulfonic acids at 140 ℃, and isolating the free acid at 10 ℃; yield 93%. Another process starts from 1-chloro-2,4-dinitrobenzene, which, as an alcoholic solution, is reacted with sodium sulfite solution to form 2,4-dinitrobenzenesulfonic acid, from which the end product is obtained by reduction with iron according to BE′CHAMP.
