Monosodium Phosphate (MSP)

Description

Monosodium phosphate, also known as sodium dihydrogen phosphate, is a mineral compound and one of the most useful compounds among other phosphates (disodium phosphate and trisodium phosphate), which contains anhydrous and hydrated salts. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.

Physical and Chemical Properties:

Monosodium phosphate is a solid compound in powder or crystalline form that is generally colorless and odorless. This chemical product has very good solubility in water but is completely insoluble in substances such as ethanol, ether, and chloroform. This compound is a kind of emulsifier. Therefore, it has wide applications in various industries. Other properties of monosodium phosphate include pH control because this chemical product is acidic, in fact, it is more acidic than other sodium phosphates. This chemical can also be used as a high-capacity buffer; The most important physical and chemical properties can be summarized in the following table:

Chemical Structure Depiction

Synthesis and Production of Monosodium Phosphate:

This chemical is obtained from the neutralization of trisodium phosphate by phosphoric acid:

Na₂HPO₄ + H₃PO₄ → 2NaH₂PO₄

Also, heating this salt to 169 ° C causes the formation of disodium pyrophosphate:

2 NaH₂PO₄ → Na₂H₂P₂O₇ + H2O

Monosodium Phosphate Uses:

In addition to its special properties, monosodium phosphate has several applications in industrial and food grades. In this section, we try to acquaint you with some of the applications of this chemical product:

Food:

Monosodium phosphate is one of the chemical compounds required by the human body. In fact, this chemical can be used to supply the body with the amount of phosphorus it needs.
