  • Method for the manufacturing of alkali monofluorophosphate
    Patent number: 5393506
    Abstract: In a method for manufacturing alkalimonofluorophosphate of general formula M.sub.2 PO.sub.3 F(I), where M stands for the cation of a metal of the first main group of the periodic system, in particular potassium, a reaction mixture containing alkali metal cations M, phosphate, fluoride, particularly in the form of alkali hydroxide, phosphoric acid and hydrofluoric acid, and water, the molar ratio of M:P:F being (2.+-.0.1):(1.+-.0.05):(1.+-.0.1) and the molar ratio of water:P being at least 1:1, is heated to a temperature of 150.degree. C. to 400.degree. C. Alkalimonofluorophosphate of general formula (I) occurs, with evaporation of water, as a reaction product, which is then isolated.
