Ammonium phosphate

                                           Ammonium phosphate


Ammonium phosphate is an ammonium salt of orthophosphoric acid. It is a highly unstable compound with the formula (NH4)3PO4. Because of its instability, it is elusive and of no commercial value. A related "double salt", (NH4)3PO4.(NH4)2HPO4 is also recognized but is too unstable for practical use. Both triammonium salts evolve ammonia. In contrast to the unstable nature of the triammonium salts, the diammonium phosphate (NH4)2HPO4 monoammonium salt (NH4)H2PO4, are stable materials that are commonly used as fertilizers to provide plants with fixed nitrogen and phosphorus.

PREPARATION OH AMMONIUM TRIPHOSPHATE

Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution:
H3PO4 + 3 NH3 → (NH4)3PO4(NH4)3PO4 is a colorless, crystalline solid. The solid, which has the odor of ammonia, is readily soluble in water. The salt converts to diammonium hydrogen phosphate (NH4)2HPO4. On the other hand, ammoniated superphosphates are produced by adding normal superphosphate or triple superphosphate to the mixture. The production of liquid ammonium phosphate and ammoniated superphosphates in fertilizer mixing plants is considered a separate process.
Ammonium phosphates are consumed almost exclusively as fertilizers, supplying both nitrogen and phosphorus to plants. Driven by population growth and strongly influenced by general economic drivers, global consumption of ammonium phosphate will continue to grow at an average annual growth rate of 2.3% during the period 2015-24. China is the largest producer, consumer, and exporter. Africa and the Middle East are among the regions with the largest increases in ammonium phosphate production, consumption, and exports in the past five years, and this trend will continue in the forecast period.This report provides an excellent insight into the global market for ammonium phosphate. It has been compiled using primary industry research and brings together elements of other IHS Markit reports in the Chemical Economics Handbook (CEH) fertilizers'related reports.

Sulphuric acid

                                        Sulphuric acid Sulfuric acid  (alternative spelling  sulphuric acid ), also known as  oil of vitriol , is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO 4 . It is a colorless, odorless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic. Its corrosiveness can be mainly ascribed to its strong acidic nature, and, if at a high concentration, its dehydrating and oxidizing properties. It is also hygroscopic, readily absorbing water vapor from the air.   Upon contact, sulfuric acid can cause severe chemical burns and even secondary thermal burns; it is very dangerous even at lower concentrat...
