Dipotassium phosphate

Tetrapotassium peroxodiphosphate is produced by electrolysis of a solution containing dipotassium phosphate and potassium fluoride (52). Alkalinity favors the formation of the P20 g anion, whereas the PO anion is produced in larger yields in acidic solution. It is therefore possible to obtain an 80% yield of K4P20g by choosing the proper conditions. The tetrapotassium peroxodiphosphate can be crysta11i2ed from solution by evaporation of water to form a slurry. The crystals can be separated from the slurry and dried. The material is noncorrosive and cannot be catalyticaHy decomposed by iron ions. 

Potassium tripolyphosphate [13845-36-8] K P O q, also used in detergents, is made by dehydrating an equimolar mixture of mono- and dipotassium phosphates. 

DKP = dipotassium phosphate Poly = polyphosphate and SALP = sodium aluminum phosphate. Other terms may be found in the text. 

NOTE An alternative to MBT-based inhibitors for glycol are phosphate-based formulations. An example is based on 30% dipotassium phosphate and 5% TTA, used at 2,000 ppm product. 

Where low-toxicity, propylene glycol is employed (rather than the more common ethylene glycol), the inhibitor is more usually simply 30% dipotassium phosphate (K2HP04), so as to maintain the low-toxicity feature, and is then used at 3,000 ppm product. This same inhibitor is employed in the food industry in sweet water systems.

Production. Xanthan gum is produced by the microorganism X. campestris, originally isolated from the mtabaga plant. The gum is produced commercially by culturing X. campestris purely under aerobic conditions in a medium containing commercial glucose, a suitable nitrogen source, dipotassium phosphate, and appropriate essential elements. When the fermentation is complete, the gum is recovered from the fermentation broth by precipitation with isopropyl alcohol, and dried, milled, tested, and packed.
