Potassium monofluorophosphate

The monofluorophosphates can be prepared by neutralization of monofluorophosphoric acid (1). Sodium monofluorophosphate [7631 -97-2] is prepared commercially (57) by fusion of sodium fluoride and sodium metaphosphate, and the potassium monofluorophosphate [14104-28-0] can be prepared similarly. Insoluble monofluorophosphates can be readily prepared from reaction of nitrate or chloride solutions with sodium monofluorophosphate. Some salts are prepared by metathetical reactions between silver monofluorophosphate [66904-72-1] and metal chlorides. 

The appUcation of so called wandering corrosion inhibitors is among the modem methods of the damaged structure repair. The sodium monofluorophosphate is used for this purpose [USA patent no 5071579], as well as the potassium monofluorophosphate, patented in Europe by Domtar Inc. The clean dry surface of concrete is covered by the monofluorophosphate water solution or in the form of gel the phosphate ions infiltrate the concrete and reconstmct the passive film on reinforcement.

Monofluorophosphates of ammonium, lithium, sodium, potassium, silver, calcium, strontium, barium, mercury, lead, and benzidine have been described (70) as have the nickel, cobalt, and ziac salts (71), and the cadmium, manganese, chromium, and iron monofluorophosphates (72). Many of the monofluorophosphates are similar to the corresponding sulfates (73).

A simpler and technologically superior approach is the measurement of the direct electrical conductance. The background conductivity of the mobile phase is electronically subtracted, not requiring a suppressor device. One example of direct conductivity detection is the simultaneous determination of potassium nitrate and sodium monofluorophosphate in dentrifices [76]. Alendronate, a bisphonate, can be directly detected in intravenous solutions and tablets using an anion-exchange column and conductivity detection [77]. Another example, from one of the author s (JA) laboratory is shown in Figure 5.3. Direct conductivity detection makes it possible to selectively detect choline in the presence of an equal molar amount of an antibiotic which is not detected.

A well-formulated product will ensure a level of fluoride in the saliva above 0.02 ppm for several hours [18]. Fluoride ions are present in toothpaste formulations largely in the form of stannous fluoride (Snp2), sodium monofluorophosphate (NajPOsF), and sodium fluoride (NaF). But we can also find in the literature potassium fluoride, lithium fluoride, aluminum fluoride, zinc fluoride, acidic phosphate fluoride, ammonium fluoride, titanium tetrafluoride, and amine fluoride.
