2,2'-Benzidinedisulfonic acid C화학적 특성, 용도, 생산
화학적 성질
PURPLE CRYSTALLINE POWDER용도
4,4'-Diaminobiphenyl-2,2'-disulfonic acid hydrate is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dyestuff. Benzidine-2,2' -disulfonic acid is used in the production of yellow and red azo dyes.생산 방법
2,2'-Benzidinedisulfonic acid is made from the potassium or sodium salt of 3- nitrobenzenesulfonic acid by a gradual reduction using zinc dust and sodium hydroxide solution in a dilute aqueous solution. The product is subsequently rearranged using hydrochloric acid or dilute sulfuric acid. Electrochemical or catalytic reductions are also possible.일반 설명
