This page contains information on the chemical Sodium hyponitrite including: 2 synonyms/identifiers. Gary L. Stucky, Jack L. Lambert, R. Dean Dragsdorf (1969), "The hydrates of sodium hyponitrite". Sodium hyponitrite is a solid ionic compound with formula Na2N2O2 or (Na+)2[ON=NO]2−. [1], The cis isomer was also obtained in 1996 by C. Feldmann and M. Jansen by heating sodium oxide Na2O with 77 kPa of nitrous oxide N2O (laughing gas) in a sealed tube at 360 °C for 2 hours. The trans form is more common, but the cis form can be obtained too, and it is more reactive than the trans form. [1][2], The trans isomer is colorless and soluble in water and insoluble in ethanol and ether. Sodium hyponitrite. M. N. Hughes and H. G.

Other methods included oxidation of a concentrated solution of hydroxylamine with sodium nitrite in an alkaline medium[citation needed]; or electrolysis of sodium nitrite. Sodium hyponitrite is a solid ionic compound with formula Na 2N 2O 2 or (Na )2[ON=NO] . Part I. CS1 maint: multiple names: authors list (. CopyCopied, CSID:8210166, http://www.chemspider.com/Chemical-Structure.8210166.html (accessed 07:55, Nov 27, 2020) An earlier method, published by D. Mendenhall in 1974, reacted gaseous nitric oxide (NO) with sodium metal in 1,2-dimethoxyethane, toluene, and benzophenone. James Riddick Partington and Chandulal Chhotalal Shah (1931), "Investigations on hyponitrites. [1], InChI=1S/H2N2O2.2Na/c3-1-2-4;;/h(H,1,4)(H,2,3);;/q;2*+1/p-2, Except where otherwise noted, data are given for materials in their, Egon Wiberg, Arnold Frederick Holleman (2001). There are three main procedures for generating the hyponitrite salts of sodium (Figure 46). The salt was then extracted with water. [13] The anhydrous substance can be obtained by drying the hydrates over phosphorus pentoxide and then heating them to 120 °C. Journal of the American Chemical society, volume 77, issue 19, pages 4976–4980. The cis-Na 2 N 2 O 2 salt can be produced by reaction of sodium metal with nitric oxide in liquid NH 3, or by reacting Na 2 O with N 2 O at high temperatures (220,222). [1], There are cis and trans forms of the hyponitrite ion N2O2−2. No predicted properties have been calculated for this compound. ... Ionic, chemical compound with the formula Cd 2. EnvironmentalChemistry.com. [13], Sodium hyponitrite (trans) in solution is decomposed by carbon dioxide CO2 from air to form sodium carbonate. sodium hyponitrite. [3][4], Sodium hyponitrite (trans) is conventionally prepared by reduction of sodium nitrite with sodium amalgam. 100435-20-9 - ONBXDIFCNSOWQF-UHFFFAOYSA-N - Sodium hyponitrite - Similar structures search, synonyms, formulas, resource links, and other chemical information. Solid ionic compound with formula or 2 [ON=NO] 2−. Polyhedron, volume 8, issue 21, pages 2621-2622. (London) 1963, 1686 and references therein. Journal of the Chemical Society D: Chemical Communications, volume 1969, issue 2, page 80a. [8][2], The anhydrous cis salt is stable up to 325 °C, when it disproportionates to nitrogen and sodium orthonitrite:[2], It is generally more reactive than the trans isomer. What is the chemical formula for lithium hyponitrite?. [9] The method was later modified to use pyridine[citation needed]. [15][1], The cis isomer of sodium hyponitrite is a white crystalline solid, insoluble in aprotic solvents, and (unlike the trans isomer) decomposed by water and other protic solvents.
