Sodium thiocyanate

Sodium thiocyanate


Name: Sodium thiocyanate
Chemical formula: NaSCN
Molecular weight: 81.07
Physicochemical properties: sulfides, nitrides and cyanides are decomposed at 287 ~C. Reaction with acids and strong oxidants. White crystalline or powder with a relative density of 1.735 and a melting point of about 287 C. It is easily soluble in water, ethanol, acetone and other solvents. The aqueous solution is neutral. It reacts with iron salt solution to form blood red iron thiocyanide, which does not react with ferrous salt. Form yellow sodium bisulfate with concentrated sulfuric acid. It reacts with cobalt salt to form dark blue cobalt thiocyanide, silver salt to form white silver thiocyanide, and copper salt to form black copper thiocyanide precipitation. It is easily deliquescent in air. Toxic, chronic poisoning with thyroid injury, the highest allowable concentration in the air is 50mg/m3.
