Characteristic:colorless monoclinic system crystal.The melting point is approximately 172℃.It is easily dissolved in the water and reduces the temperature due to massive heat absorption.It also can be dissolved in the alcohol and?? acetone.Under the low temperature, it can crystallize into?? half-hydrate(KSCN.0.5H2O).It is steady under the temperature of 29-6.8℃ and it becomes blue when the calores cense degree is about 430℃,but it can become colorless again when it is cold.It will decompose when the temperature rises to 500℃.It produces blood-red ferric rhodante with molysite and does not react with ferric .It is easily deliquesced so it should be sealed for storage.
Application:General:Mainly used in sectors of pharmaceuticals,pesticede,textile,electroplanting,phogography etc
Raw material for the prodution of a number of a number of pharmaceutical products.
Raw material for the production of a number of herbicides and fungicides and pesticides
Photographic industry for tonong ,sensibilisation
Packing:25kg paper bags with polyethylene lining.
