7558-80-7 NaH2PO4 98% Monosodium Phosphate In Food
NaH2PO4 98%min white powder monosodium phosphate Buffering agent Emulsifier 7558-80-7
Properties
Anhydrous products are white powder, and melting point is at 190 ℃. Dihydrate products is colorless crystal, relative density at 1.915 g/cm3, melting point at 57.4℃. It is soluble in water, not soluble in organic solution. Sodium dihydrogen phosphate (NaH2PO4 · 2H2O) is also known as monosodium phosphate and monobasic sodium phosphate. It is colorless crystalline or white crystalline powder, odorless, soluble in water, and its aqueous solution is acidic, almost insoluble in ethanol. When heated, it loses crystallization, and water can be decomposed into acidic sodium pyrophosphate (na3h2p2o7).
Disodium hydrogen phosphate neutralization method: dissolve disodium hydrogen phosphate dodecahydrate with water at the ratio of 3:2, remove the insoluble matter through filtration, add the filtrate into the neutralizer, slowly add phosphoric acid under stirring for neutralization reaction, control the pH value at 4.2-4.6, evaporate and concentrate the reaction solution until it forms a crystalline film, cool and crystallize, and centrifuge to obtain disodium hydrogen phosphate dihydrate. Then anhydrous sodium dihydrogen phosphate was prepared by drying at 100 ℃. The mother liquor can be returned to dissolve disodium hydrogen phosphate.
