Sodium Nitrite
Properties:
Colorless transparent or white tinged with yellow rhombic crystal,Sp.Gr.2.17(20 ), M.P.271 , soluble in water, slightly soluble in alcohol and ether, deliquescence, when heated at 320 ), decomposes to O2.N2, Na2O NO or NO2.Easily burn and explode when mixed with organic materials. It gives off nitrogen oxide when burns. Absorbs oxygen from air, evolves as NaNO2, it is strong poison, do not contact with skin to avoid pollution or toxicant.
Applications:
It is used as the raw material for producing potassium nitrate, mining explosive and picric acid; as nitrification agent for producing dye intermediates; as antifoaming agent, discoloring agent, clearing agent and oxidation flux tin glass industry.
Handling and Storage:
Packed in 25/50/1000kg pp bags, Store it in the shady, cool and dry storehouse. Keep away from kindling material and heat source, the packaging should be sealed, can't keep in touch with the air, should preserve with flammable, combustible substance and reducing agent ,etc. , prohibit to store and transport together with other things; carefully load and unload in order to prevent damaging the container and package.
