Hot Sale 99% min Sulfanilic Acid for Sale
Product description:
Sulfanilic acid is white to gray white powder, and after absorbing water in air, it becomes white crystal. It has a crystalline water of molecule. It loses crystalline water at 100 C. It begins to decompose carbonization at 300 C, dissolves in cold water, dissolves in boiling water, insoluble in ethanol, ether and benzene. It has obvious acidity and solubility. In sodium hydroxide solution and sodium carbonate solution. It can also be used to produce azo dyes, and can also be used as pesticides against wheat rust.It is relocated by the reaction of aniline with sulfuric acid and then relocated. The aniline is dripped into concentrated sulfuric acid, and the reaction mixture is poured into cold water to obtain colorless precipitation of p-aminophenylsulfonic acid. After the cooling is filtered, the p-aminophenol sulfonic acid is dried.
