sodium phosphonato phosphate decahydrate - Preparation Method
Open Data Verified Data
soda ash was added to a neutralizer, heated and dissolved with stirring, and then phosphoric acid was added for neutralization reaction to produce disodium hydrogen phosphate. The pH at the end of the reaction was controlled to be 8.2 to 8.6. After decolorization and filtration, the disodium hydrogen phosphate solution is concentrated and dried, and then sent to the blade mechanism to form a sheet, and then sent to the polymerization furnace to heat and polymerize to generate sodium pyrophosphate. After cooling, crushing, screening, prepared anhydrous sodium pyrophosphate products. Alternatively, disodium hydrogen phosphate is heated at 200-300 °c to obtain anhydrous sodium pyrophosphate. Anhydrous sodium pyrophosphate was dissolved in water and concentrated to give crystalline sodium pyrophosphate.
