    Brief Overview

    Tripotassium phosphate, also known as tribasic potassium phosphate, appears as a deliquescent white powder. It is a water-soluble ionic salt and is slightly hygroscopic in nature. It is available in hydrated form as a monohydrate and dihydrate. Tripotassium phosphate is used as a food additive for its properties as an emulsifier, foaming agent, and whipping agent. It should not be used if one has low levels of calcium or high levels of potassium or phosphorus.

    Manufacturing Process

    Tripotassium phosphate can be manufactured through the reaction between ammonium phosphate and potassium chloride.
    (NH4)3PO4 + 3KCl → K3PO4 + 3NH4Cl

    Another production process of potassium phosphate has two steps:

    1. Wet phosphoric acid is put into an ultrasonic reactor for ultrasonication at the temperature of 2 - 80 °C with a reaction time of 10 - 120 minutes.

    2. The product is cooled to room temperature, and precipitates are leached. Thus, a filter liquor is obtained. Potassium hydroxide, potassium carbonate, or potassium bicarbonate is used to regulate the pH value of the filter liquor and generate precipitates. Then, the new filter liquor is concentrated, evaporated, crystallized, and separated to obtain potassium phosphate.

    Food Industry

    Tripotassium phosphate is used as a food additive for its properties as an emulsifier, foaming agent, and whipping agent in the food industry. It is used to produce processed meat products, processed cheeses, and canned soups. It is used as an acidity regulator for regulating the acidity or alkalinity of a food. It is used as an emulsifier agent that forms or preserves a mixture of substances normally incapable of being mixed. Tripotassium phosphate is used as a sequestrant agent that can control the availability of a cation. It is used as a stabilizer that maintains the uniform dispersal of substances in food products. Tripotassium phosphate is found in cooked and cured meats, milk and cream products, and drinking chocolate.

    Agriculture Industry

    Tripotassium phosphate is used as a soluble fertilizer to make fertilizer compounds of Nitrogen and phosphorous pentoxide.

    Cosmetics Industry

    Tripotassium phosphate is a buffering agent in cosmetics.

    Medical Industry

    Tripotassium phosphate is a medication used to treat or prevent hypophosphatemia (low blood levels of phosphorus). It is also added to intravenous (IV) fluids given to people who cannot eat or drink anything.

    Other Applications

    Tripotassium phosphate is found in liquid soap and refined gasoline products. Tripotassium phosphate is a component in antifreeze and de-icing products, cleaning and furnishing care products, plastic and rubber products, and food packaging. It is also used in pharmaceutical and paper-making industries.
