Potassium Polyphosphate

Kurrol s potassium polyphosphate through a whole series of intermediate polyphosphates. The fact that potassium trimetaphosphate is formed by direct heating of K4(P40i2) to temperatures above 200°C is an indication of the occurrence of radical-like fragments as intermediate products 119). 

In the system (KII2P04—H3P04) high-molecular potassium polyphosphates are formed on heating, together with acid mono- and di-phosphate but only a little oligophosphate (363). But tertiary P04 tetrahedra occur not only in phosphates with Na P < 1. They can also be detected in Graham s and Kurrol s salt with Mr P = 1 (224, 284, 85, 86) and are also formed in melts of anhydrous trimetaphosphates, especially in a dry atmosphere (364). Their equilibrium concentration in the melt is about 2%. 

Three crystalline forms of potassium polyphosphate also exist (22, 29)... 

Some allowed food additives, for example, E-451 and F-452, contain the following PolyPs triphosphates - pentasodium triphosphate and pentapotassium triphosphate polyphosphates - sodium polyphosphate, potassium polyphosphates and calcium polyphosphate. 

In addition, a potassium polyphosphate solution of 0-26-27 grade has been produced from superphosphoric acid and potassium hydroxide it contains a mixture of ortho, pyro, and higher polyphosphates.

Builders are formulated into detergents mainly to sequester hardness ions (Ca2+, Mg2+) found in water, as well as to disperse the dirt and soil particulates in the wash water. Common builders used in liquid detergents are sodium and potassium polyphosphates (except in the U.S.), carbonates, aluminosilicates (zeolite A), silicates, citrates, and fatty acid soaps [5],... 

Maddrell s salt, which are interpreted as showing that kinetic effects are responsible for difficulties in converting the cyclic trimer into the linear polymeric forms. The potassium polyphosphate samples (Kurrol s salt) obtained from the fusion of potassium sulphate and phosphoric acid have chains terminated by OSOJ groups, according to i.r. spectra. Kinetic studies show a first-order dependence of polyphosphate concentration in the hydrolysis of Graham s salt to give trimetaphosphate and short-chain species. The vaporization of sodium metaphosphate from a Knudsen cell leads to predominantly monomeric, with some dimeric, species, according to mass-spectrometric data. ...

Manning (1969) showed that when f < 1 then F= V2 (1 — V2 ) whereas if > 1 then r= l/4f. He compared these expectations with experimental data available to him for a variety of polyelectrolytes sodium polyvinyl sulfate and sodium polyacrylate (of various degrees of neutralization a) and potassium polyphosphate and DNA, having values ranging from 0.29 to 4.20, with good results. Also the expectations for the osmotic coefficients of the sodium polyacrylate and polymethacrylate were well vindicated.

Long-chain potassium polyphosphate, (KP03) , can be prepared simply by heating potassium dihydrogen orthophosphate when repeated condensation takes place to give a continuous chain of tetrahe-dra (5.142). Potassium polyphosphate can also be prepared by reaction (5.143) in which the heat of combustion of white phosphorus is used to assist the condensation of the PO4 tetrahedra as they are formed in embryo. 

The viscosities of polyphosphate solutions are very dependent upon the thermal history and the exact composition (M2O/P2O5) of the solid phase. If potassium polyphosphate, (KP03) , for example. 

Micronutrient fertilisers can be made by incorporating snitable micronutrient compounds into bulk-blended fertilisers. Boron phosphate, BPO4, is an excellent slow-release source of boron. Relatively insoluble crystalline mixed-metal potassium polyphosphates can also be used. Micronutrient phosphate glasses also have valuable slow-release characteristics (Section 12.9). The required metals are introduced into the very sUghtly water-soluble glasses in the form of their oxides, for example, ZnO, CuO, MnOj, M0O3 or BjOj [37] (Table 12.26).

In an attempt to obtain direct evidence for the presence of cross-linking in potassium polyphosphates crystallized from ultraphosphates melts, two tools were chosen. Cross-linking should in theory be observed by either phase chemistry or X-rays. Also, the existence of end and middle group phosphorus is well established...
