This should be considered when choosing a container for sodium azide solutions. It is an ionic substance, is highly soluble in water, and is very acutely toxic. [12], It is also used as a mutagen for crop selection of plants such as rice,[13] barley[14] or oats. Nitrogen gas is extremely stable and will not try to coordinate to anything. Sodium azide is a white crystalline solid that is highly toxic when ingested or inhaled. %PDF-1.6 %���� Silver(1+) azide. Molecular Formula: CsN 3: Synonyms: caesium azide. The azide functional group can thereafter be converted to an amine by reduction with either SnCl2 in ethanol or lithium aluminium hydride or a tertiary phosphine, such as triphenylphosphine in the Staudinger reaction, with Raney nickel or with hydrogen sulfide in pyridine. [N-]=[N+]=[N-] 13863-88-2. 59, No. This colorless salt is the gas-forming component in many car airbag systems. 2 Names and Identifiers Expand this section. It is an ionic substance, is highly soluble in water, and is very acutely toxic. Contents. CopyCopied, IVRMZWNICZWHMI-UHFFFAOYSA-N �� Molecular Weight: 174.926 g/mol. CopyCopied, CSID:30959, (accessed 06:23, Nov 13, 2020) Sodium azide is the inorganic compound with the formula NaN₃. Molecular Formula: AgN 3: Synonyms: SILVER AZIDE.

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. 1 Structures Expand this section. [21], Sodium azide solutions will react with metals to form metal azides, which can be shock sensitive and explosive. [15], Sodium azide has caused deaths for decades. The common synthesis method is the "Wislicenus process", which proceeds in two steps from ammonia. h�bbd``b`n�oA�u ��$�� �H�~��\u �U �b},�@����m �e �Hb;�Pq�`H?Hw6�R��_b`bdxr#Չ�L�� ��} endstream endobj startxref 0 %%EOF 134 0 obj <>stream Each azide is linked to six Na+ centers, with three Na-N bonds to each terminal nitrogen center.[7]. Treatment of sodium azide with strong acids gives hydrazoic acid, which is also extremely toxic: Aqueous solutions contain minute amounts of hydrogen azide, the formation of which is described by the following equilibrium: Sodium azide can be destroyed by treatment with nitrous acid solution:[9]. It may be fatal in contact with skin or if swallowed. Two crystalline forms are known, rhombohedral and hexagonal. Silver azide (dry) [Forbidden] More... Molecular Weight: 149.889 g/mol. Con-tact with water or acid causes release of hydrazoic acid (HN. Create . Sodium azide is a useful probe reagent and a preservative. CTK4C0927. [22], "NaN3" redirects here. Sodium azide is used in airbags because it explodes so well, mercury azides detonate if you do nothing with them, etc. Azide can adopt formal charges, yes, but that's distinct from a nitrogen coordinating to a nitride. It is used for the preparation of other azide compounds. Component Compounds: CID 33558 (Azide ion) CID 5354618 (Cesium) Dates: Modify: 2020-09-05. This method is suited for laboratory preparation of sodium azide: Alternatively the salt can be obtained by the reaction of sodium nitrate with sodium amide.[8]. Component Compounds : CID 33558 (Azide ion) CID 23954 (Silver) Dates: Modify . This can also create a dangerous situation when azide solutions are disposed down the drain into the sanitary sewer system. Curtius and Thiele developed another production process, where a nitrite ester is converted to sodium azide using hydrazine. The toxicity of this compound is comparable to that of soluble alkali cyanides. [18] No toxicity has been reported from spent airbags. Determination of Azide in Aqueous Samples by Ion Chromatography with Suppressed Conductivity Detection. [16] It is a severe poison. It possesses the NFPA 704's highest rating of 4 on the health scale. ACMC-1BUCT. ��d)��w�@A�T �V�����µZ�-fR6ˈT?&�Ȱcɝ,��E�%�z6 ( Older airbag formulations contained mixtures of oxidizers and sodium azide and other agents including ignitors and accelerants. Silver monoazide. In the latter case, innocuous sodium silicates are generated. Q14773521. Rodriguez-Kabana, R., Backman, P. A. and King, P.S., Plant Disease Reporter, 1975, Vol. [1][6] Both adopt layered structures. [5], Sodium azide is an ionic solid. The salt readily dissolves in water to yield the azide anion (N-3). 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. 87 0 obj <> endobj 115 0 obj <>/Encrypt 88 0 R/Filter/FlateDecode/ID[<88264A1DDBDA11DB929B000D935892E4>]/Index[87 48]/Info 86 0 R/Length 116/Prev 434578/Root 89 0 R/Size 135/Type/XRef/W[1 2 1]>>stream 2020-10-31. [17] Even minute amounts can cause symptoms. Metal in the plumbing system will react, forming highly sensitive metal azide crystals which can accumulate over many years. AKOS025294946. Due to its explosion hazard, sodium azide is of only limited value in industrial-scale organic chemistry. 2 Names and Identifiers Expand this section. 3 Chemical and Physical Properties Expand this … 2005-08-08. The azide anion is very similar in each form, being centrosymmetric with N–N distances of 1.18 Å. �d��R�����-/�mU��=��OQKb��hf_��,�. Contents. [19], It produces extrapyramidal symptoms with necrosis of the cerebral cortex, cerebellum, and basal ganglia. 528-532 (, Last edited on 6 September 2020, at 15:28, National Institute for Occupational Safety and Health, "The crystal structures of lithium, sodium and strontium azides", "Studies of the Effect of Sodium Azide on Microbic Growth and Respiration: I.
