The origin of our products: monoammonium phosphate (MAP)

MAP - or monoammonium phosphate - is a product which derives from phosphorus (P).



MAP - or monoammonium phosphate - is a product which derives from phosphorus (P).

MAP is generated by the extraction of phosphatic rocks and through a reaction process between phosphoric acid and ammonia. It is presented in granular form.

Phosphorus is naturally available in the form of phosphate: the limited and ever diminishing quantities of phosphorus in the world make it an extremely precious resource for the development of life.

The products generated by the phosphate transformation process serve as raw material to produce other goods. The MAP is used in many production sectors: almost all of it is used in the production of fertilizers for agriculture, or it is used, for example, in the production of food and animal supplements, in the field of fire protection.

The main MAP producing countries are:

  • Russia,
  • Morocco,
  • the United States,
  • Saudi Arabia,
  • China.

Large deposits of phosphate rock enable the extraction of phosphorus and its transformation depending on the destination and market demand.

The divisions


The monoammonium phosphate (MAP) is the main raw material used in the production processes of ProPHOS Chemicals: it is involved in the production of microgranular fertilizers of the DEMA division and for the production of ABC extinguishing powders.

In addition, monobasic ammonium phosphate is also used to produce flame retardants for the KALI division.

The recovery of raw material


The combination of the increased demand for phosphates to help meet the food needs of the world’s population, and its scarcity in nature, causes the market to fluctuate substantially.

A conscientious use of the raw material becomes an essential requirement to limit the depletion of reserves. For this reason, we have developed a production technology able to create micro-granular fertilizers, which allows to reduce the excessive presence of substances in the soil and consequently reduce the waste of raw materials, including phosphorus.

Also, in the field of fire protection, the recovery procedures of the MAP have been initiated, obtaining the authorization for the reserve of spent dust to allocate the waste in collection and recovery centers.
