Monosodium orthophosphate

Sodium Pyrophosphates. Known pyrophosphate compounds in the Na20—H2O—P20 system are given in Table 10. Commercially important sodium pyrophosphates include tetrasodium pyrophosphate (TSPP), Na4P20y, and disodium pyrophosphate, Na2H2P20y, commonly referred to as sodium acid pyrophosphate (SAPP). These are prepared industrially by thermal dehydration of disodium and monosodium orthophosphate, respectively. Tetrasodium pyrophosphate exists in five crystalline modifications, only one of which is stable at room temperature.

The list of raw materials that could be used in this process is extensive. Soda ash or Trona could have been substituted for sodium hydroxide. Under some conditions limestone, CaC03, could be substituted for quicklime, CaO. There are several grades of phosphoric acid that might have been used, but I always insisted upon food grade materials even though they cost somewhat more than industrial grades. It is also possible to use sodium phosphates as monosodium orthophosphates for the sodium hydroxide and phosphoric used in the first plant. And, of course, it was possible to use calcium phosphates such as monocalcium orthophosphates. One requirement was paramount. If uniform melt was to form on the surface...

Uses. The principal use of monosodium phosphate is as a water-soluble soHd acid and pH buffer, primarily in acid-type cleaners. The double salt, NaH2P04 H PO, referred to as hemisodium orthophosphate or sodium hemiphosphate, is often generated in situ from monosodium phosphate and phosphoric acid in these types of formulations. Mixtures of mono- and disodium phosphates are used in textile processing, food manufacture, and other industries to control pH at 4—9. Monosodium phosphate is also used in boiler-water treatment, as a precipitant for polyvalent metal ions, and as an animal-feed supplement. 

The orthophosphates are inorganic salts of orthophosphoric acid which result when one or more of the hydrogen ions of the acid are replaced by other positively charged ions. They are most commonly available in the three sodium forms of the salt monosodium phosphate (in which one sodium ion substitutes for a hydrogen), disodium phosphate, and trisodium phosphate. These are usually abbreviated as MSP, DSP, and TSP, respectively.
