Pyrophosphoric acid

CAS: 2466-09-3
Molecular Formula: H4P2O7
Molecular Weight: 177.98
Product description:Colorless viscous liquid, generate crystallization, colorless vitreous. Pyrophosphate root has a strong coordination.Relative density of 1.70 reagent phosphate in heated to 250 DHS C 6-7 h, dehydration reaction, with ammonium hydroxide and silver nitrate test, have a pure white precipitate out, reaction to the end. After the reaction, in drier cooled to 50 to 60 DHS C, that content is between 52% and 55% pyrophosphate of finished products.1. Used as analytical reagent, such as masking agent, used for the preparation of organic phosphate. 2. Used in copper plating process, adjust the pH value of solution, also can be applied to other electroplating. 3. Used in catalysts, metal refining, organic peroxide stabilizer.
