Phosphamic acid

The water-soluble flume retardants are most easily applied by impregnal-ing the fabric wilh a water solution of a retardant, followed by drying. The water-soluble flame retardants used must widely for textiles are listed in Tahle 3. Less commonly used retardants include sulfamates of urea or other amides and amines aliphatic amine phosphates, such as triethanolamine phosphate, phosphamic acid tamido phosphoric acid. and its... 

According to H. Biltz, ammonia acts energetically on phosphorus pentoxide at ordinary temp., forming a dark reddish-brown mass of phosphamic acid, which, when treated with water, forms phosphine, yellow phosphorus, and a reddish flocculent mass of phosphorus tetritoxide—not red phosphorus as H. S chill supposed. A 0-06 per cent, yield of the same oxide was formed by heating phosphorus pentoxide at 250° either in vacuo or in a current of air, carbon dioxide, hydrogen, oxygen, or steam. Traces were also produced by dissolving the pentoxide in water or soda-lye.

Dibenzyl- and /(-substituted dibenzylphosphonyl groups have been used to protect the amino group . Those derivatives are obtained by reaction of the corresponding dibenzylphosphonyl chloride with the amine in pyridine. The benzyl or j>-substituted benzyl groups are removed by catalytic hydrogenation to yield the corresponding phosphamic acid which is very acid sensitive. Treating the phosphamic acid with aqueous solution (pH 4) at 25 results in the formation of free phosphoric acid and the amine, within five to ten minutes, in quantitative yield (reaction 14) . It has been shown that the di-... 

The solid produced by interaction of phospham and hydrogen sulfide at red heat is probably a trimeric triphosphatriazine such as phospham. The solid ignites in slightly warm air or in dinitrogen tetraoxide, and is violently oxidised by nitric acid. 

For reactions with ammonia analogous products such as HN=PCl3 and HN==P(NH,)j were proposed, but characterization was hampered by incomplete reactions, separation-resistant mixtures, and sensitivity to moisture. Furthermore, gradual polymerization occurred with loss of ammonia to yield phospham , a poorly characterized solid of approximate formula (PNtH) as the ultimate product. If instead of free ammonia its less reactive conjugate acid is used, reaction with PCI, proceeds at a moderate rale and the results are more definitive ...
