Product Description

Potassium dihydrogen phosphate cas 7778-77-0

Potassium phosphate is a potassium phosphate, which varies depending on the number of potassium atoms:

1. Dipotassium hydrogen phosphate K2HPO4 (Phosphoric acid molecule two hydrogen atoms are replaced by potassium atoms)

2. Potassium dihydrogen phosphate KH2PO4 (phosphoric acid molecule of a hydrogen atom is replaced by a potassium atom)

3. Potassium phosphate (phosphoric acid molecules are all three hydrogen atoms are replaced) Molecular formula: K3PO4.

production method

(1) neutralization method 50 $ phosphoric acid solution was added to the corrosion-resistant reaction tank, according to phosphoric acid: potassium hydroxide = 1: 2 molar ratio by adding: 30% potassium hydroxide solution, stirring and neutralization reaction, control pH8 .5 ~ 9 or so, generate a dipotassium hydrogen phosphate solution. Then sent to secondary neutralizer by adding 30% potassium hydroxide solution for neutralization reaction, the end point of control pH = 14, resulting in tripotassium phosphate solution, concentrated by evaporation until the relative density of 1.38 ~ 1.46, and then cooled crystallizer After cooling to below 60 ℃, centrifugal separation, obtained tribasic phosphate finished. Can also be without cooling the crystallizer directly hot concentrated potassium tripolyphosphate solution obtained by centrifugation. The separated mother liquor is returned to the evaporator.


Tripotassium phosphate is used as a food additive in the food industry as an emulsifier and a strong agent for potassium. Prepared flour products with alkaline water, flavoring agent, meat glue, buffer. Anti-oxidant synergist, chelating agent. Tripotassium phosphate can be used medically as a pharmaceutical excipient and a chemical reagent.
