産(chǎn)品标題1.jpg

White or a little buff fine crystal. The relative molecular weight is 69.0 and density is 2.168. It is unscented with a little saline taste, easy to be deliquescenced and to dissolve in water. The melting point is 271 land decomposition temperature is 320笆.It has property ofoxidability and reducibility. It can be slowly oxidized into sodium nitrite in the air, and become diamino compound composed with ammonia under low temperature.
