Rodriguez-Kabana, R., Backman, P. A. and King, P.S., Plant Disease Reporter, 1975, Vol. This should be considered when choosing a container for sodium azide solutions. Two crystalline forms are known, rhombohedral and hexagonal. 3 Chemical and Physical Properties Expand this … Curtius and Thiele developed another production process, where a nitrite ester is converted to sodium azide using hydrazine.
6, pp. Determination of Azide in Aqueous Samples by Ion Chromatography with Suppressed Conductivity Detection. In the first step, ammonia is converted to sodium amide: The sodium amide is subsequently combined with nitrous oxide: These reactions are the basis of the industrial route, which produced about 250 tons per year in 2004, with production increasing owing to the popularization of airbags.[5]. Contents. CopyCopied, CSID:30959, http://www.chemspider.com/Chemical-Structure.30959.html (accessed 06:23, Nov 13, 2020) It may be fatal in contact with skin or if swallowed. Sodium azide is a white crystalline solid that is highly toxic when ingested or inhaled.

Create . [21], Sodium azide solutions will react with metals to form metal azides, which can be shock sensitive and explosive. ��d)��w�@A�T �V�����µZ�-fR6ˈT?&�Ȱcɝ,��E�%�z6 ( Sodium azide increases cyclic GMP levels in brain and liver by activation of guanylate cyclase. 13863-88-2.

[12], It is also used as a mutagen for crop selection of plants such as rice,[13] barley[14] or oats. 2005-08-08. Molecular Formula: AgN 3: Synonyms: SILVER AZIDE. This colorless salt is the gas-forming component in many car airbag systems. It is an ionic substance, is highly soluble in water, and is very acutely toxic.
Molecular Formula: CsN 3: Synonyms: caesium azide. Q14773521. Each azide is linked to six Na+ centers, with three Na-N bonds to each terminal nitrogen center.[7].

It is not to be confused with, Except where otherwise noted, data are given for materials in their, Automobile airbags and airplane escape chutes, CS1 maint: multiple names: authors list (, Applications of sodium azide for control of soilborne pathogens in potatoes. This colorless salt is the gas-forming component in many car airbag systems. CopyCopied, InChI=1S/N3/c1-3-2/q-1 The Na+ ion has octahedral geometry. Sodium azide is used in airbags because it explodes so well, mercury azides detonate if you do nothing with them, etc. The sodium that is formed is a potential hazard alone and, in automobile airbags, it is converted by reaction with other ingredients, such as potassium nitrate and silica. [19], It produces extrapyramidal symptoms with necrosis of the cerebral cortex, cerebellum, and basal ganglia. Older airbag formulations contained mixtures of oxidizers and sodium azide and other agents including ignitors and accelerants. [1][6] Both adopt layered structures. 59, No. CTK4C0927. [22], "NaN3" redirects here. It is an ionic substance, is highly soluble in water, and is very acutely toxic. Metal in the plumbing system will react, forming highly sensitive metal azide crystals which can accumulate over many years. Silver(1+) azide. 2 Names and Identifiers Expand this section. In the latter case, innocuous sodium silicates are generated. In hospitals and laboratories, it is a biocide; it is especially important in bulk reagents and stock solutions which may otherwise support bacterial growth where the sodium azide acts as a bacteriostatic by inhibiting cytochrome oxidase in gram-negative bacteria; however, some gram-positive bacteria (streptococci, pneumococci, lactobacilli) are intrinsically resistant. Sodium azide is a versatile precursor to other inorganic azide compounds, e.g., lead azide and silver azide, which are used in explosives. Structure, properties, spectra, suppliers and links for: Azide, 7782-79-8. [18] No toxicity has been reported from spent airbags. It is used for the preparation of other azide compounds. This can also create a dangerous situation when azide solutions are disposed down the drain into the sanitary sewer system. Sodium azide is the inorganic compound with the formula NaN₃. [11], It is used in agriculture for pest control of soil-borne pathogens such as Meloidogyne incognita or Helicotylenchus dihystera. [10] Sodium azide is also used in airplane escape chutes. Molecular Weight: 174.926 g/mol.
Sodium azide is a useful probe reagent and a preservative.
The common synthesis method is the "Wislicenus process", which proceeds in two steps from ammonia. Nitrogen gas is extremely stable and will not try to coordinate to anything. [5], Sodium azide is an ionic solid.
