Product Description

High Purity Dipotassium Hydrogen Phosphate Trihydrate

Product Overview

Dipotassium Hydrogen Phosphate Trihydrate, its chemical formula is K2HPO4. 3H2O, and its molecular weight is 28.22. The appearance is colorless flake or needle like crystal or white granule. Deliquescence, easy to dissolve in water (1g dissolved in 3mL water), aqueous solution is weak alkaline, 1% aqueous solution pH is about 9, insoluble in ethanol. The density is 2.33g/cm3. Burning potassium K4P2O7 after burning. It is used as analytical reagent, pharmaceutical raw material, buffering agent, chelating agent, yeast feed, emulsifying salt and antioxidant synergist in food industry. China's hygienic standard for the use of food additives (GB 2760 - 1996) stipulates that it can be used for powdered fat with a maximum dosage of 19.9g/kg. Let the phosphoric acid react with potassium carbonate solution and add a small amount of KOH to the solution so that phenolphthalein is rosy red and evaporated and crystallized.
