Organics nitrogen-containing

The interaction between HC [the initial and global reductant in reaction (1)] and N02 leads to the formation of an organic nitrogen-containing compound (RNO,), which subsequently suffers decomposition, releasing some CxIIvO oxygenate and NO. This is the crucial point we shall see that NO is formed, but not N2 in this fundamental step.

The chlorophyll molecule comprises a central magnesium ion surrounded by an organic nitrogen-containing cyclic structure called haem (or heme ), (V) which is based on a porphyrin ring. 

All positively charged nitrogen species and all organic nitrogen-containing compounds are readily converted to nitrite and then to nitrate in soil. Because of this ready conversion, all are sources of nitrogen for plants. 

Some organic nitrogen-containing compounds (nitriles, ni-troalkyls, amides, etc.) are the rare exceptions to this rule. For example, for acetonitrile, c = 36 and rj = 0.3 cP at room temperature. Elowever, the poor electrochemical stability of these compounds prevented them from being used in batteries.

In tests made by TVA and IFDC of many other organic nitrogen-containing compounds as fertilizers, some proved readily available, some slowly available, some inert, and some toxic. Among those that showed promise as slow-release fertilizers were oxamide, glycouril, cyanuric acid, ammeline, and ammelide. For lack of an economical process, none of these materials has been manufactured commercially for fertilizer use. 

A number of metal nitrosyl complexes react with activated alkyl halides to yield, ultimately, organic nitrogen-containing products. The most widely studied reagent is [Ru(NO)2(PPh3)2] (229), though other compounds such as [CoCl(NO)(CO)2] (230) and [Fe(NO)(CO)3] (231) have been used. These reactions have been discussed in depth elsewhere (6). Another reaction of some industrial importance is the catalytic reaction of NO gas with alkenes. Over Ag20 or PbO the product from propene is acrylonitrile. In a study of this type of reaction (232),...

Synthesis of carbon nitrides has been attempted for example by the pyrolysis of organic nitrogen-containing compounds such as melamine-formaldehyde resin and subsequent shock compression of the obtained residues [85]. However, no tetrahedral carbon nitride could be detected in the reaction products. In a similar approach, L. Maya et al. obtained a carbon nitride with trigonally coordinated carbon by the pyrolysis of organic compounds at 700°C and 225 MPa pressure... 

Zimmer AG [99, 100] claim that PTT can be heat stabilised by contacting the polymer with a melt unstable, organic nitrogen-containing stabilising compound e.g., 1-aminoethanol, triacetonediamine, 4-aminosalicyclic acid, or a melt stable alcoholate such as sorbitol or polyvinyl alcohol.

It is no accident that few of the foods and beverages listed in Table 13-4 are basic. The often disagreeably bitter taste associated with bases may be an evolutionary adaptation that warns against alkaloids, a family of organic, nitrogen-containing bases that are often poisonous. A few alkaloids, such as caffeine, are consumed for pleasure, but usually these are acquired tastes. Other alkaloids include morphine, nicotine, and cocaine. 

Nylons are often used in electrical products, such as electrical connectors, terminal blocks, smah electrical housings, switch components, wire ties, and other industrial parts, where thermal stability and fire resistance are priorities. Because of this practical interest, the thermal stability and flame retardancy of nylons have been studied extensively. Halogen compounds are effective flame retardants for polyamides [14-17], but they have limited utility because their combustion products are toxic. Alternative flame retardants are used with polyamides, such as phosphorus- and nitrogen-containing substances. The most important organic nitrogen-containing flame retardants are melamine and its derivates [14, 18-20]. However, these traditional flame retardants are outside the scope of this chapter.
