KSCN |
Molecular weight |
97.18 |
Physicochemical properties |
Colorless monoclinic structure, relative density 1.886, melting point 172.3 ° C, soluble in water, and cooled by a large amount of heat absorption, also soluble in alcohol and acetone, semi-hydrated crystals at low temperature (KSCN·0.5H 4O), stable at -29.5 ° C - 6.8 ° C, turn blue when burned to about 430 ° C, but then become colorless after cooling, such as heat to 500 ° C decomposition, in case of iron salt to form blood red thiocyanate Iron, no reaction when it meets ferrous salt. |
Uses |
Used as a leaching agent in the electroplating industry, it can also be used in refrigerants, as well as in the dye industry, photographic industry, pesticides and steel analysis. |
