monosorbxp-4 - Preparation Method
Open Data Verified Data
industrial production methods include disodium hydrogen phosphate neutralization method and soda ash neutralization method.
- disodium hydrogen phosphate neutralization method: add water to dissolve disodium hydrogen phosphate dodecahydrate in a ratio of 3:2, remove insoluble matters by filtration, add the filtrate to a neutralizer, slowly add phosphoric acid under stirring for neutralization reaction, the pH value was controlled at 4.2 to 4.6, and the reaction solution was concentrated by evaporation until a crystalline film was formed. After cooling crystallization, centrifugation was carried out to obtain sodium dihydrogen phosphate dihydrate. The product was then dried at 100 °c to obtain a final anhydrous sodium dihydrogen phosphate. The mother liquor may be returned for dissolution of disodium hydrogen phosphate.
- soda ash neutralization method: the extraction phosphoric acid is added to the neutralization reactor, and the soda ash solution is slowly added under stirring for neutralization reaction to generate sodium dihydrogen phosphate, which is filtered and evaporated and concentrated, the crystals were precipitated by cooling to 60-70 ° C. And centrifuged to obtain sodium dihydrogen phosphate dihydrate. After air drying, prepared anhydrous sodium dihydrogen phosphate product.

monosorbxp-4 - Introduction
Tasteless. Micro moisture absorption. Heating to 225-250 ℃ to produce acidic sodium pyrophosphate, 350-400 ℃ to form sodium metaphosphate. Median lethal dose (rat, muscle) 250mg/kg. Easily soluble in water, the aqueous solution is acidic, can agglomerate in humid air, and is almost insoluble in ethanol. When heated to 100 ℃, it dehydrates, generates sodium pyrophosphate at 190-210 ℃, and decomposes into sodium metaphosphate at 280-300 ℃. Solubility in water: 850g/L (20°C)
