Technical Document

Brief Overview 

Dipotassium phosphate, also known as potassium phosphate dibasic. The dipotassium phosphate formula is K2HPO4. It is highly water-soluble and frequently used as a fertilizer and food additive. It functions as an effective buffering agent and sequestrant for a wide range of uses, including a balancing agent. It is a common source of phosphorus and potassium.

Manufacturing Process

Dipotassium phosphate is produced by the stoichiometric reaction of phosphoric acid with two equivalents of potassium hydroxide. This neutralization reaction produces the aqueous salt of dipotassium phosphate and water. Water is then removed to obtain the fine white powder of potassium hydrogen phosphate. By controlling the amount of potassium hydroxide added, potassium dihydrogen phosphate and tripotassium phosphate can be produced.

Food Industry

In food processing, dipotassium phosphate is used as a food additive to lower acid levels. Dipotassium phosphate can also be a stabilizer in non-dairy creamer and energy drinks. In dairy products, dipotassium phosphate is a buffering agent, sequestrant, and emulsifier. Dipotassium Phosphate is also applied in coffee, creamer, and meat processing.

Agricultural Industry

Dipotassium phosphate enhances plant nutrition and is safe to be used in irrigation and spraying systems. Dipotassium phosphate can be mixed with all water-soluble fertilizers except calcium and magnesium, as their phosphates are insoluble in water and will be precipitated.
