产品特性 Product Features

纯品为无色透明斜方晶系结晶,水溶液呈酸性。不溶于醇、丙酮和氨水[2]   。有吸湿性,吸湿后固结成块。加热到513℃以上完全分解成氨气、氮气、二氧化硫及水。与碱类作用则放出氨气。与氯化钡溶液反应生成硫酸钡沉淀。也可以使蛋白质发生盐析。

The pure product is colorless transparent orthorhombic crystal, and the aqueous solution is acidic. Insoluble in alcohol, acetone and ammonia. It is hygroscopic, and it will be consolidated into agglomerates after moisture absorption. It will be decomposed into ammonia gas, nitrogen gas, sulfur dioxide and water when heated above 513 ℃. Interaction with alkali releases ammonia. Reacts with barium chloride solution to form barium sulfate precipitate. Proteins can also be salted out.
