Phosphoryl fluoride (commonly calledphosphorus oxyfluoride) is a compound with the chemical formulaPOF3. It is a colorless gas that hydrolyzes rapidly. It has acritical temperature of 73 °C and acritical pressure of 4.25bars.[1]
Phosphorus oxyfluoride is prepared by partialhydrolysis ofphosphorus pentafluoride.
Phosphorus oxyfluoride is the progenitor of the simple fluorophosphoric acids by hydrolysis. The sequence starts withdifluorophosphoric acid:
The next steps givemonofluorophosphoric acid andphosphoric acid:
Phosphoryl fluoride combines withdimethylamine to produce dimethylaminophosphoryl difluoride(H3C−)2N−P(=O)F2 anddifluorophosphate andhexafluorophosphate ions.[2]
