Acid rain and air pollution are very important problems that must be solved in the future because such pollution has major effects on terrestrial and aquatic ecosystems. At present, one of the most significant problems is removal of NOx, which are produced during high-temperature combustion and are an important group of air contaminants. In particular the decomposition or reduction of nitrogen monoxide (NO) is a major target to be achieved.

SAFETY PROFILE Poison by intraperitoneal route. An irritating poison to skin, eyes, and mucous membranes. Reacts explosively with aniline, diallyl sulfide, and hydrazine hydrate. Explosive reaction with propiononitrale after heating to 105°C for 24 hours. Violent reaction with dibenzoyl peroxide + 4-toluic acid. When heated to decomposition it emits toxic fumes of Br and NOx. See also BROMIDES and NITROGEN MONOXIDE. 

SAFETY PROFILE A poison. Moderately toxic by inhalation. When heated to decomposition it emits toxic fumes of NOx. See also NITROGEN MONOXIDE.

Decomposition of sodium trioxodinitrate in the presence of [Ni(CN)4] gives [Ni(CN)3(NO)] by direct displacement of CN by NO . The NO produced by the reaction between nitrogen monoxide and hydroxylamine is also trapped by tetracyanonickelate(II) in a direct displacement reaction, but the trapping efficiency differs in the two cases. This may reflect the difference in the electronic states of NO formed in the two reactions, NO from HNO being a singlet species and NO from NOH being a triplet. ...

Whereas the distribution profile of the radicals in the bulk cannot be determined, the distribution of the products of their reaction with oxygen can. In other words, the degree and distribution of oxidative degradation in the bulk can be determined by measuring the distribution of the hydroperoxides and of their decomposition products using infrared spectroscopy (FTIR) [43, 44]. In Figure 21.1 the oxidation products after NO (nitrogen monoxide) treatment for a new prosthesis are reported [41-42]. 

PRACTICE EXAMPLE B N2O3 is an unstable oxide that readily decomposes. The standard reaction entropy for the decomposition of N2O3 to nitrogen monoxide and nitrogen dioxide at 25 °C is AjS = 138.5 J mol What is the standard molar entropy of N203(g) at 25 °C ... 

Decomposition Decomposes within 6 months at 60°C complete decomposition in 3.75 h at 150°C may produce HCN oxides of nitrogen, oxides of phosphoms, carbon monoxide, and HCN. 

Decomposition Toxic gases and vapors (such as oxides of nitrogen, phosgene, nitrosyl chloride, chlorine, and carbon monoxide) may be released when chloropicrin decomposes. 

PTAD reacts with 625 at elevated temperature to give only low yields of bicyclic compound 626. The low yield is presumably caused by decomposition of PTAD to carbon monoxide, nitrogen, and phenylisocyanate (Scheme 101) <1999JHC627>.
