¡¾English name¡¿ sodium azide
CAS Code: 26628-22-8
¡¾Molecular Formula¡¿ NaN3
¡¾¡¿ Molecular weight or atomic weight of 65.02
Density¡¿ ¡¾1.846
¡¾Properties¡¿ six square colorless crystals, there are poisonous!
¡¾Preparation¡¿ by amino or source of sodium and the role of nitrous oxide obtained.
¡¾Properties¡¿ heating decomposed into sodium and nitrogen. Soluble in water, the water solubility is as follows: 10 ℃, 40.16%; 17 ℃, 41.7%. pK = 4.8. Aqueous solution containing NH3, heated to 37 ℃, ammonia Yat away. Soluble in liquid ammonia, slightly soluble in ethanol, insoluble in ether.
Sodium azide is stable, but is still affected by an explosion on i***ct, producing nitrogen gas. Aqueous solution of sodium azide was alkaline (alkali weak acid salt) solid is ionic crystals can be used to protect the air bag car crash
¡¾Uses¡¿ an important pharmaceutical intermediate for the synthesis of methyl-mercapto-tetrazole, tetrazole acetic acid, 5 - Mercapto-1H-1-methanesulfonic acid disodium salt, cephalosporin for the amine side chain, azide , lead and high-purity sodium azide, are an important intermediate of cephalosporins. It is also widely used in automated blood cell counter antiseptic sterilization airbags and agricultural insecticides fungicides.
Sodium azide (NaN3) is a respiratory inhibitor, can cause genetic mutations, get a higher mutation frequency, and with no residue.
Within the car's airbag sodium azide (NaN3) and other substances. When the car at high speeds, under severe i***ct, these substances are rapidly decomposition reaction, producing a large number of gas, filled with air bags. [Sodium azide nitrogen and the decomposition of solid sodium]
2NaN3 (s) ¡ú 2Na (l) 10 3N2 (g) "
Solid Solid ---- --- ---- gas upon i***ct, the solid rapidly decompose and emit a lot of nitrogen.
Aqueous solution can make the protein denaturation, in the biochemical analysis of protein used for precipitation.
For the preparation of lead azide and medicine. |
