使用
Potassium hydrogen phosphate trihydrate is widely used to prepare buffer solutions in molecular biology, biochemistry and chromatography. It is involved in the production of trypticase soy agar and then utilized for culturing bacteria. As a food additive, it is used in dry powder beverages, mineral supplements and imitation dairy creamers. It is also used as a stabilizer for non-dairy coffee creamers. Further, it is a common source of phosphorous and potassium.
主な応用
Dipotassium hydrogen phosphate trihydrate can be used to:
As a corrosion inhibitor. Dipotassium hydrogen phosphate forms a passivation film on the metal in alkaline solutions with low chloride contamination, which slows down the corrosion of carbon steel
[1].
As a catalyst. Dipotassium hydrogen phosphate powder catalyses the conversion of stable phosphoryl compounds to dialkyl (E, Z)-2-(1-acetyl-2-naphthalenyl)-2-butenedioate under thermal and microwave conditions in a solvent-free system
[2].
As a reducing agent. Dipotassium hydrogen phosphate (K
2HPO
4.3H
2O) was used for the efficient reduction of graphene oxide nanosheets. Dipotassium hydrogen phosphate itself and the prepared graphene are environmentally friendly and cheap
[3].
As a nutrient. Used as a nutrient in antimicrobial media.
