Nitrogen oxide,penta

Mixtures of potassium and solid carbon dioxide are shock-sensitive and explode violently on impact, and carbon monoxide readily reacts to form explosive carbon-ylpotassium (potassium benzenehexoxide) [1]. Dichlorine oxide explodes on contact with potassium [2]. Potassium ignites in dinitrogen tetraoxide or dinitrogen penta-oxide at ambient temperature and incandesces when warmed with nitrogen oxide or phosphorus(V) oxide [3]. At —50°C, potassium and carbon monoxide react to give dicarbonylpotassium, which explodes in contact with air or water, or at 100°C. At 150°C, the product is a trimer of this, potassium benzenehexoxide. The just-molten metal ignites in sulfur dioxide [4]. 

In the oxide of trimethylamine, (GH3)3NO, the electron diffraction data of Lister and Sutton show that the NO bond distance is 1 36 A which is approximately the value for a single bond. If the nitrogen were penta valent, the bond would be double and the distance less and evidently, in the amine oxides, structures of the type (GH3)3N—O, make a large contribution. In nitrosyl chloride and nitrosyl bromide the NO bond length is decreased, from i ii to 1 14 A, which suggests that the bond is a hybrid of the structures... 

TETRADECYL ALCOHOL or n-TETRADECYL ALCOHOL (112-72-1 27196-00-5, mixed isomers) Alcohols are reducing agents.

Depending on the conditions of preparation, Th(N03)4 crystallizes from solutions of thorium hydroxide (or from HNO3 solutions of moderately calcined oxide) with varying contents of water of crystallization. When a not too acid solution is concentrated by evaporation, Th(N03)4 crystallizes in the cold with 12 moles of HgO. A solution evaporated at IS C yields the penta-hydrate, which is stable to 80°C if heated in an atmosphere free of COg. At higher temperatures, it converts to the trihydrate, and between 125 and 150°C, to the hemihydrate. Above 150°C the remaining water is split off, together with nitrogen oxides. 

No differences in reactivity among perfluoro-, tetrafluoro-, 4-bromotetrafluoro-, ortetrafluoro-4-methylaniline in oxidations at nitrogen are apparent. Therefore, these derivatives of penta-fluoroaniline are presented together. 

Most decaphenylmetailocenes also exhibit an unsurpassed thermal stability for sandwich complexes. The decaphenyl Ge, Sn, and Pb derivatives do not decompose until above 350°C (under nitrogen) (39), in contrast with around 100°C for the decabenzyl analogs (106). For sym-penta- and decaphenylferrocene and -ruthenocene an extraordinary degree of thermal and oxidative stability is noted (40) they are unchanged in air ( ) at 315°C and volatilize only at 250-300° C in the mass spectrometer. 

Cacodylic acid is reduced to cacodyl when treated -with an excess of sodium hypophosphite in hydrochloric acid solution, Cacodyl may be obtained from dimethylarsine by the action of oxides of nitrogen, aqueous chromic acid, le peroxide, cacodyl chloride, auric chloride, or potassium ferricyanide. It also results w hen cv/cZopentamethyl-penta-arsine is distilled under atmospheric pressure in a carbon dioxide atmosphere, the decomposition commencing at 270° C. ...

Aqueous Cu and (edta)Fe efficiently catalyse the oxidation of hydroxyl-amine to nitrogen by hexacyanoferrate(iii). A mechanism involving association between the catalyst and an intermediate NHgO was proposed penta-cyanoferrates and other secondary reaction products have no significant catalytic activity. ...
