Introduction

Sodium cyanide is white or slightly colored in lumps or crystalline granules with weak bitter almonds. Soluble in water, the solution was weakly alkaline, and slow Slow reaction to produce highly toxic hydrogen cyanide gas, the solution in the presence of air can dissolve gold and silver, slightly soluble in ethanol. Sodium cyanide is mainly used for refining Gold, silver and other precious metals and quenching, and for plastics, pesticides, pharmaceuticals, dyes and other organic synthesis industry. China's major sources of cyanide are safe Emblem, Hebei, Shanxi, Henan, Inner Mongolia, the main importer is Japan.

Classification of Class 6.1 (Toxic Substances) in accordance with the United Nations Model Regulations on the Transport of Dangerous Goods (UNRTDG) Goods, United Nations number 1689. Swallowing, skin contact, inhalation of sodium cyanide fatal and highly toxic to aquatic organisms and has long lasting Ring; sodium cyanide is not flammable, but with acid, acidic salt contact decomposition of toxic and flammable hydrogen cyanide, and nitrate, chlorate, peroxide, etc.

Strong oxidants react violently, with the risk of explosion.

The State Council March.2011 issue of "dangerous chemicals safety management regulations" [State Council Decree No. 591] provides the inspection and quarantine departments Responsible for the inspection of import and export of dangerous chemicals and their packaging.
