Dipotassium Phosphate Usage and Synthesis.

Potassium dihydrogen phosphate is a substance widely used in agriculture and chemical industry. In agriculture, it can improve soil fertility, is easily absorbed and utilized by crops, enhances the ability of crops to resist cold, drought, pests and diseases, and improves the quality of crops, etc., and is widely used in a variety of crops such as rice, wheat, corn, cotton, soybeans and peanuts.

In the chemical industry, potassium dihydrogen phosphate is mainly used as a raw material for potassium metaphosphate, dipotassium hydrogen phosphate, tripotassium phosphate and potassium pyrophosphate. Utilizing wet purification of phosphoric acid to produce potassium dihydrogen phosphate can effectively reduce the production cost, and has a fairly huge development space.

Uses of Dipotassium Phosphate.

It is a texture improver, which has the effect of increasing the complex metal ions, pH value, and ionic strength of foodstuffs, thus improving the adhesion and water-holding property of foodstuffs. It can be used in phytolipid powder with a maximum use level of 19.9g/kg.

Used in boiler water treatment. It is used as phosphorus and potassium regulator and bacterial culture medium in medicine and fermentation industry. It is the raw material for manufacturing potassium pyrophosphate. It can be used as liquid fertilizer, corrosion inhibitor of ethylene glycol antifreeze. Feed grade is used as feed nutrition supplement.

In the food industry, it is used as a raw material for the preparation of alkaline water for pasta products, as a fermentation agent, as a flavoring agent, as a bulking agent, as a mild alkaline agent for dairy products, and as a yeast food. Used as buffering agent and chelating agent.

Characteristic of Dipotassium Phosphate.

Produt Method of Dipotassium Phosphate.

Under constant stirring, add potassium carbonate solution to 30% of the reaction in phosphoric acid solution, neutralization endpoint for pH 8.5 ~ 9.0 (phenolphthalein indicator just showed red); neutralization solution is concentrated to 120 ~ 124 ° C after filtration to remove insoluble material, and then cooled to 20 ~ C below the crystal; centrifugal separation, drying of the product, the mother liquor is sent to the neutralization process for reuse.
