| 2,2'-ベンジジンジスルホン酸 (30%水含む) Usage And Synthesis |
外観 | うすい黄色~褐色粉末~結晶 | 化学的特性 | PURPLE CRYSTALLINE POWDER | 使用 | 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. | 調製方法 | 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.
| 一般的な説明 | Leaflets or prisms or light purple powder. | 空気と水の反応 | Insoluble in water. | 火災危険 | Flash point data for 2,2'-Benzidinedisulfonic acid are not available; however, 2,2'-Benzidinedisulfonic acid is probably combustible. | 燃焼性と爆発性 | Non flammable | 安全性プロファイル | A severe eye irritant.
