Peroxomonophosphate

However, the peroxomonophosphate ion decomposes relatively rapidly ia aqueous solution. A mixture of peroxodiphosphoric and peroxomonophoshoric acids can be produced by treatiag a cold phosphoric acid solution with elemental fluorine (qv) (49). Peroxodiphosphoric acid is not produced commercially. Ammonium, lithium, sodium, potassium, mbidium, cesium, barium, 2iac, lead, and silver salts have all been reported. The crystal stmctures of the ammonium, lithium, sodium, and potassium compounds, which crysta11i2e with varyiag numbers of water molecules, have been determined (50).

A preliminary study of the oxidation of nitrite, sulphite, selenite and phosphite claims that one oxygen atom is transferred per mole of peroxomonophosphate reacting. A slight kinetic study of the nitrite reaction was made. 

Moreover, the electrolysis of phosphate solutions at acidic pH leads to the generation of peroxomonophosphate [7]. Nevertheless, the process is less efficient than the generation of peroxodiphosphate in alkaline solutions, due to the lower chemical stability of the peroxomono compound.

The peroxomonophosphate (PMS) oxidation of L-ascorbic acid (H2A), oxidation of indole, and the /H 50-tetraphenylporphyrin-FeCl3 (TPP)-catalysed oxidations of indole " and indole-3-acetic acid in HjO-MeCN are effected easily compared to the corresponding oxidations by peroxodisulfate. The catalysed reactions of indole and indole-3-acetic acid are of fractional order in both substrate and catalyst. The rate of oxidation of H2A is retarded by H" " ions. The rates of oxidation of indole and catalysed oxidation of indole 3-acetic acid decrease with increasing percentage of MeCN. 

Catalytic oxidation of H2O by peroxodiphosphate has been studied under acid conditions where competing hydrolysis to peroxomonophos-phate is avoided. The stoichiometry (36) has been established and the rate law found to be first order in [P20g ] and [Ag ] from initial rate measurements, H2P20g and HP20g being the most important species. Oxidations of aliphatic aldehydes with peroxomonophosphate have been studied mechanistically. ...
