Potassium phthalate Use and Manufacturing

Mainly used in medicine industry, K2HPO3 could be developed as corrosion inhibitor for antifreeze, nutrient for antibiotic medium, phosphorus and potassium regulator for fermentation industry, feed additive, etc. In the food industry, it is used as raw material for the preparation of alkaline water for pasta products, fermentation agent, flavoring agent, leavening agent, milder and alkaline agent for dairy products, yeast food. K2HPO3 also can be used as deiron agent for preparation of talcum powder. In addition, K2HPO3 was used as water treatment agent, pH regulator, a buffer chelating agent as well as a feed additive. Furthermore, K2HPO3 can also be used as phosphating treatment of metal and plating additive.
