Harris Phosphorus

Phosphorus pentabromide [7789-69-7] M 430.6, m <100 , b 106 (dec). Dissolved in pure nitrobenzene at 60°, filtering off any insoluble residue on to sintered glass, then crystallised by cooling. Washed with dry Et20 and removed the ether in a current of dry N2. (All manipulations should be performed in a dry-box.) [Harris and Payne J Chem Soc 3732 1958]. Fumes in moist air because of hydrolysis. HARMFUL VAPOURS.

Biochar from dairy manure also has pofenfial for environmenfal remediation or for creating slow release phosphorus fertilizers (Cau and Harris, 2010). Dairy manure was converted by heating at temperatures below pyrolysis temperatures (< 500 °C) and in the presence of air. The potential benefit for lowering GHGs was nof defermined but the products have the potential of creating new markets for manure.

Point Defect Generation During Phosphorus Diffusion. At Concentrations above the Solid Solubility Limit. The mechanism for the diffusion of phosphorus in silicon is still a subject of interest. Hu et al. (46) reviewed the models of phosphorus diffusion in silicon and proposed a dual va-cancy-interstitialcy mechanism. This mechanism was previously applied by Hu (38) to explain oxidation-enhanced diffusion. Harris and Antoniadis (47) studied silicon self-interstitial supersaturation during phosphorus diffusion and observed an enhanced diffusion of the arsenic buried layer under the phosphorus diffusion layer and a retarded diffusion of the antimony buried layer. From these results they concluded that during the diffusion of predeposited phosphorus, the concentration of silicon self-interstitials was enhanced and the vacancy concentration was reduced. They ruled out the possibility that the increase in the concentration of silicon self-interstitials was due to the oxidation of silicon, which was concurrent with the phosphorus predeposition process.

Phosphorylation of XLVII with phosphorus oxychloride in pyridine solution, followed by hydrolysis to remove the methyl and isopropylidene residues, gave D-ribose 5-phosphate (XLVIII) which, as its barium salt, was found to be identical with the barium salt of the D-ribose phosphate from inosinic acid. By way of further confirmation of the structure of D-ribose 5-phosphate, Levene, Harris and Stiller129 showed that in methanolic hydrogen chloride solution both the natural and synthetic material mutarotated in a manner characteristic of a sugar which can form only a furanoside.

However, Harris and Williams recently reported the designed synthesis and spectral characteristics of the first ANSA cyclotriphosphazene52,53), by the reaction of 3-amino-1 -propanol with monomethyl-pentachlorocyclotriphosphazene 54 The announcement of this discovery was made at the International Conference on Phosphorus Chemistry held in Nice, September, 1983, and it made some outstanding colleagues sceptic. ..

Phosphorus pentodde-Phosphoric acid. Anhydrous phosphoric acid (orthophosphoric acid) is prepared by dissolving 25 g. of P Os in 33 g. of 85% phosphoric acid. - Wilson and Harris used this reagent to phosphorylate pyridoxamine dihydrochloride with phosphoryl chloride the yield whs very low.

Examples of anthropogenic phosphate minerals are shown in Figure 9.14 (Harris, 2002 University of Florida). Figure 9.14a shows patina of black, poorly crystalline apatite on the surface of an oyster shell located near the bottom of an early American mound, which once served as a refuse pile (about 5,000 YBP). Bones of fish and other animals were discarded in the pile and became the source of phosphorus that precipitated on the nnderlying shell. Note that oyster shells are composed of calcium carbonate, npon which phosphate readily adsorbs and precipitates (scale bar = 5 mm). Figure 9.14b shows vivianite as precipitate on an aggregate from stream sediment near Lake Okeechobee, Florida, collected a short distance downstream from where a dairy barn floor routinely flushed manure. Soils and stream sediments in the area are naturally low in phosphorus (scale bar = 1 mm).
