Usage And Synthesis
Outline

Ammonium thiocyanate is colorless lustrous monoclinic flaky or columnar crystal with the chemical formula being NH4SCN and the molecular weight of 76.12. At 92 ºC, it is rhombohedral crystal with the melting point of 147 ºC (decompose at 170 ºC), the relative density of 1.3057 and the refractive index of 1.685. It is easily soluble in water and will have endothermic reaction when being dissolved in water. It is soluble in alcohol, alkali metal hydroxide, acetonee, pyridinee and liquid sulfur dioxidee but insoluble in chloroforrm. Its solution exhibits red color upon exposure to sunlight.In case of ferric iron, it generates iron thiocyanate of blood red color and can be measured by colorimetric quantification according to the color of standard solution. When being heated to 140 ºC, it can generate Thioureaa while it will be decomposed into ammoniaa, hydrogen sulfide and carbon disulfide at 176 ºC. It is easily to be deliquescent in the air and therefore should be sealed with isolation from acid. Production method: have carbon disulfide and ammoniaa in a pressurized reactor react for 20 hours at the temperature of 30 ºC to obtain it; alternatively, have sulfur powder, sodium cyanidee and ammonium chloride reacted with water with the temperature being maintained at 110 ºC to obtain the final product. The main purposes: It can be used as the polymerization catalysts for organic synthesis, dyeing spreading agent, herbicide, analytical reagents such as for determination of mercuryy, silver as well as trace iron. It can also be used for the production of thiocyanate and thiocyanate complex salt. It also has certain dissolving capability for silver halide. Its concentrated solution has also the ability of dissolving the gelatin. It can also be used as photographic liquid and golden color matching of the printing paper, printing of cotton and steel pickling.
