Abstract

Phosphonitrilic esters are prepared by reacting an alcohol with a phosphonitrilic halide in the presence of an alkali metal carbonate. An organic solvent may be used. Temperatures of 60-120 DEG C. are mentioned. Some or all of the halogen may be replaced by ester groups. Suitable phosphonitrilic halides include: those of formula (PNX2)n where the halogen atom X may be Cl, Br or F and n is an integer not less than 3 and preferably not greater than 20 and mixed halides of this type; phosphonitrilic halides containing other end groups such as those of types (PNX2)pHCl and (PNX2)p.PCl5 (p = an integer); cyclic structures having at least two fused polyphosphazene rings such as 2,2,4,6,6,8,10,10,12 - nonachloro - (4,8,12-nitrilo) - 2,4,6,8,10,12 - cyclohexaphosphazene; and alkyl or phenyl substituted phosphonitrilic halides. Mixtures of halides may be used. Suitable alcohols include monohydric, dihydric and higher polyhydric alcohols and polyalkylene glycols, many examples being given.ALSO:Phosphonitrilic esters of polyalkylene glycols are prepared by reacting the glycol with a phosphonitrilic halide in the presence of an alkali metal carbonate. An organic solvent may be used. Temperatures of 60-120 DEG C. are mentioned. Some or all of the halogen may be replaced by ester groups. Suitable phosphonitrilic halides include: those of formula (PNX2)n where the halogen atom X may be Cl, Br or F and n is an integer not less than 3 and preferably not greater than 20 and mixed halides of this type; phosphonitrilic halides containing other end groups such as those of types (PNX2)pHCl and (PNX2)pPCl5 (p=an integer); cyclic structures having at least two fused polyphosphazene rings such as 2,2,4,6,6,8,10,10,12 - nonachloro - (4,8,12 - nitrilo) - 2,4,6,8,10,12 - cyclohexaphosphazene; and alkyl or phenyl substituted phosphonitrilic halides. Mixtures of halides may be used. Suitable polyalkylene glycols are diethylene, triethylene, polyethylene and corresponding propylene glycols, and glycerol-based polyoxyalkylene triol. In Example 7 a dipropylene glycol based epichlorohydrin-propylene oxide copolymer is reacted with a mixture of trimeric and tetrameric phosphonitrilicchlorides in the presence of Na2CO3.
