화학적 특성

화학 식량
Storage & Sensitivity
Hygroscopic. Light Sensitive. Ambient temperatures.
Soluble in water, ethanol, methanol, ammonia and acetone. Insoluble in chloroform and ethyl acetate.


Ammonium thiocyanate has many uses in manufacturing chemicals such as metal thiocyanates [CuSCN, Ca(SCN)2, NaSCN, KSCN] and in a number of pharmaceuticals. It is used in freezing solutions, pickling, printing, and as a corrosion inhibitor against acid gases. It is used in the photography industry as a stabilizer or an accelerator. It is also used in fertilizers, fabric dyeing, zinc coating, electroplating and as a separator of zirconium and hafnium as well as gold and iron. It is also used in analytical chemistry for titrimetric analysis and to determine the iron content by colorimetry in soft drinks.


Light sensitive and hygroscopic. Incompatible with strong oxidizing agents, strong acids and lead nitrate.

Thiocyanogen bromide can be generated in situ by reaction with bromine in acetic acid, e.g. in the thiocyanation of N,N-dimethylaniline to 4-N,N-dimethylaminophenylisothiocyanate: Org. Synth. Coll., 2, 574 (1943).

Also useful for the conversion of arylamines to thioureas either indirectly via benzoyl isothiocyanate: Org. Synth. Coll., 3, 735 (1955), or directly, but in lower yield, by reaction of ammonium thiocyanate with the amine in the presence of HCl: Org. Synth. Coll., 4, 180 (1963).

In combination with CAN in t-butanol, epoxides are converted to thiiranes in high yield: Synthesis, 821 (1996). The same conversion can also be effected in the presence of SbCl3 in acetonitrile: Indian J. Chem., 38B, 605 (1999). CAN also promotes the direct conversion of activated aryl systems, e.g. indoles, pyrroles and N,N-dialkylanilines to aryl thiocyanates: Tetrahedron Lett., 40, 1195 (1999).
