Physicochemical properties
|
Colorless monoclinic film or columnar crystal, shiny, relative density 1.306, melting point 149.6 ° C, soluble in water, ethanol,
liquid ammonium, acetone, hydrazine and liquid sulfur dioxide, in the case of water absorption is endothermic In case of iron salt, it forms blood red iron thiocyanate and does not react with ferrous salt. The solution is red under the action of sunlight. When heated to about 140 °C, thiourea is formed. At 170 °C, it decomposes into ammonia, which is easy to deliquesce and should be sealed. Storage. |

Uses
|
It is an auxiliary raw material for the manufacture of hydrogen peroxide, used as a dye, a polymerization catalyst for organic
synthesis, for the separation of pesticides, antibiotics, and analytical reagents. |
