Sulphur-Nitrogen-Phosphorus Compounds

Sulphur-Nitrogen-Phosphonis Compounds.—Thermolysis of compounds of the t3rpe RgPCl N—SOgX (R = Cl, Me, or Ph X = F or Cl) has been shown 2 to result in the formation of the compounds R2P(0)C1 and [NS(0)X] . Pyrolysis of phosphorus-sulphur-nitride halides with longer chains yields, amongst others, the cyclic compounds (37) and (38). The

Two routes have been described for the preparation of lA, 2,4,3A -thiadiaza-phosphetidine (37), a compound containing a sulphur-nitrogen-phosphorus four-membered ring. ... 

The main analytical technique for pesticides is gas chromatography using a variety of detectors such as electron capture for halogenated compounds, thermionic for compounds containing either phosphorus or nitrogen, and flame photometric for compounds containing sulphur or phosphorus. 

The products of hydrocarbon oxidation in SCWO are carbon dioxide and water. Heteroatoms are converted to inorganic compounds, usually acids, salts, or oxides in high oxidation states. Phosphorus is converted into phosphate, and sulphur to sulfate nitrogen-containing compounds are oxidized to nitrogen gas. Working at temperatures below 700 °C, no NOx is formed. 

Optical activity was first observed with organic compounds having one or more chiral carbon atoms (or centres) (i.e. a carbon substituted with four different groups). In the structures (1) to (17) the chiral carbons are specified with an asterisk. Subsequently compounds having chiral centres at suitably substituted heteroatoms (e.g. silicon, germanium, nitrogen, phosphorus, arsenic, sulphur, etc.) were also synthesised. Molecular dissymmetry, and hence chirality, also... 

The lunar chemistry of nitrogen, phosphorus and sulphur has been studied in less detail than that of carbon, and less information is available about the nature and distribution of the compounds of these elements. The available data, including stable isotopic distributions, have been reviewed by Kaplan64 and will not be discussed in detail here.

Organic contaminants are compounds with a carbon skeleton, usually associated with atoms of hydrogen, oxygen, nitrogen, phosphorus and sulphur (see Section... 

Sulphur/nitrogen and sulphur/phosphorus compounds Other multifunctional sulphur/nitrogen, sulphur/phosphorus-based additives have antioxidant and antiwear properties. These additives react with peroxy radicals and hydroperoxides, thus stabilising industrial lubricants and engine oils. Syntheses and generalised chemical structures are as in Reactions (4.67. 69) [64, 72, 73] ...
