Phosphorus pentafluoride - Wikipedia
Phosphorus pentafluoride is a Lewis acid. This property is relevant to its ready hydrolysis. A well studied adduct is PF 5 with pyridine. With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula [PF 4 (NR 2 )] 2.

Phosphorus trifluoride - Wikipedia
Physical properties. Phosphorus trifluoride has an F−P−F bond angle of approximately 96.3°. Gaseous PF 3 has a standard enthalpy of formation of −945 kJ/mol (−226 kcal/mol).The phosphorus atom has a nuclear magnetic resonance chemical shift of 97 ppm (downfield of H 3 PO 4).. Properties. Phosphorus trifluoride hydrolyzes especially at high pH, but it is less hydrolytically sensitive ...

Influence of Phosphorus Concentration on the Biodegradation of ...
The influence of phosphorus concentration on the biodegradation of dissolved organic matter (DOM) was discussed as a possible cause of the accumulation of chemical oxygen demand by acidic permanganate method (CODMn) in Lake Biwa. Enhancement of oxygen consumption in the biodegradation test by dissolved phosphorus (DP) was observed in Lake Biwa water with the natural bacterial community.
