It deliquesces in wet air and releases a small amount of hydrogen cyanide gas. Soluble in water, slightly soluble in alcohol, the aqueous solution is strongly alkaline and quickly hydrolyzes. Density1.857g/cm 3, boiling point 1497℃, melting point 563℃.

The "8 12" Tianjin Big Bang occurred in 20 15. At that time, it was reported that about 700 tons of sodium cyanide (cyanide) might be leaked from the warehouse. At a critical juncture, a processing team consisting of 2 17 experts from the nuclear, chemical and biological forces and IAEA personnel was dispatched to the scene urgently. Through on-site detection and emergency spraying of hundreds of tons of hydrogen peroxide to decompose, the further deterioration of the situation was stopped.
