Brief Overview

Potassium phosphate dibasic, commonly referred to as dipotassium phosphate, has the chemical formula K₂HPO₄. This compound is readily soluble in water and finds extensive applications as both a fertilizer and a food additive. It serves as a proficient buffering agent and sequestrant in various contexts, including its role as a balancing agent. Additionally, it is a widely utilized source of both phosphorus and potassium.

Manufacturing Process

Dipotassium phosphate is generated through the stoichiometric interaction of phosphoric acid with two portions of potassium hydroxide. This neutralization process yields the aqueous form of dipotassium phosphate along with water. The subsequent elimination of water results in the formation of the finely textured white powder known as potassium hydrogen phosphate. Adjusting the quantity of added potassium hydroxide allows for the production of potassium dihydrogen phosphate and tripotassium phosphate.

Food Industry

Within the realm of food processing, dipotassium phosphate serves as a food additive employed to reduce acidity levels. It also functions as a stabilizing agent in non-dairy creamers and energy drinks. In dairy products, dipotassium phosphate plays roles as a buffering agent, sequestrant, and emulsifier. Moreover, its application extends to coffee, creamers, and meat processing.

Agricultural Industry

Dipotassium phosphate contributes to improved plant nutrition and proves safe for use in irrigation and spraying systems. It is compatible with all water-soluble fertilizers, excluding calcium and magnesium, as their phosphates exhibit insolubility in water and may precipitate.
