GB 25568 2010 Na2HPO4 Dinatrium Hydrogen Phosphate
PH regualator 98% min Disodium Phophate GB25568-2010 Na2HPO4 7558-79-4 Food Grade
Properties
Disodium hydrogen phosphate is easy to be weathered in the air. When placed in the air at normal temperature, it loses about 5 crystal water to form heptahydrate. When heated to 100 ℃, it loses all crystal water to form anhydrous substance. When heated to 250 ℃, it decomposes into sodium pyrophosphate. It is easy to be weathered in the air and lose five molecules of crystal water to form heptahydrate (na2hpo4.7h2o). Soluble in water, insoluble in alcohol. The pH of 0.1-1n solution is about 9.0. At 100 ℃, it loses crystal water and becomes anhydrous substance. At 250 ℃, it decomposes into sodium pyrophosphate. The pH value of 1% aqueous solution is 8.8-9.2, insoluble in alcohol. At 35.1 ℃, it melts and loses 5 crystal water.
Application
Disodium phosphate is used in the food industry as emulsifying agent, buffering agent, and brine constituent. Examples such as processed cheeses and dairy products.
