Product Description Sodium thiocyanate is a white orthorhombic crystal or powder. The relative density is 1.735g/cm3. Melting point 287 oC. It is prone to deliquescence in the air and produces toxic gases when exposed to acid. Easy to dissolve in solvents such as water, ethanol, etc. The aqueous solution is neutral and reacts with iron salts to form red colored iron thiocyanate. It does not react with ferrous salts and reacts with concentrated sulfuric acid to form yellow It reacts with cobalt salts to form dark blue cobalt thiocyanate, and with silver or copper salts to form white silver thiocyanate precipitate or black copper thiocyanate precipitate.Used as a chemical analysis reagent, solvent for drawing polyacrylonitrile fibers, developer for color film, defoliant for certain plants, etc. In organic synthesis, it is used to convert halogenated hydrocarbons into corresponding thiocyanates. For example, reacts with sodium thiocyanate in a hot ethanol solution to obtain isopropyl thiocyanate. Similar reagents include ammonium thiocyanate and potassium thiocyanate. Sodium thiocyanate is converted to isothiocyanate (S=C=NH) when it encounters acid. After being generated in situ, it can react with amines to produce corresponding derivatives. Used as a solvent for drawing polyacrylonitrile fibers, a chemical analysis reagent, a color film processing agent, a defoliant for certain plants, and a herbicide for airport roads. It is also used in pharmaceuticals, printing and dyeing, rubber processing, black nickel plating, and manufacturing of artificial mustard oil.
