Ammonium thiocyanate Chemical Properties,Usage,Production

Chemical Properties colourless or white crystals or powder Usage Applied in the formation of novel two-dimensional Cd-SCN coordination solids with unusual and tailorable, checkerboard- or herringbone-patterned structures these structures are important steps toward technologically useful materials.1 General Description Ammonium thiocyanate is a colorless crystalline solid. Ammonium thiocyanate is soluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium thiocyanate is used in chemical analysis, in photography, as a fertilizer, and for many other uses. Air & Water Reactions Water soluble. Reactivity Profile Ammonium thiocyanate can release ammonia vapors if mixed with a chemical base or with an acid. Violent or explosive reactions have occurred when thiocyanates are mixed with oxidizing agents (such as chlorates(potassium chlorate), nitrates, nitric acid, and peroxides). Nitric acid violently oxidized a thiocyanate solution [Bretherick 1979 p. 121]. An explosion of guanidine nitrate demolished an autoclave built to withstand 50 atmospheres, in which Ammonium thiocyanate was being made from Ammonium thiocyanate and lead nitrate [C. Angew. Chem. 49:23 1936]. Health Hazard Inhalation of dust causes irritation of nose and throat. Ingestion causes dizziness, cramps, nervous disturbances. Dust irritates eyes. Can be absorbed through skin; prolonged contact may produce various skin eruptions, dizziness, cramps, nausea, and mild to severe disturbance of the nervous system. Fire Hazard Special Hazards of Combustion Products: Decomposes to form ammonia, hydrogen sulfide, and hydrogen cyanide. Oxides of nitrogen may also form. All of these products are toxic.
