Ammonium dihydrogen phosphate (ADP), also known as monoammonium phosphate (MAP) is a chemical compound with the chemical formula (NH 4)(H 2 PO 4). ADP is a major ingredient of agricultural fertilizers and some fire extinguishers. It also has significant uses in optics and electronics.
The two commercial forms of orthophosphates are monoammonium phosphate (MAP) and diammonium phosphate (DAP). Polyphosphate fertilizers contain a variety of polymeric forms mixed with some orthophosphate. Present production capacities for manufacturing ammonium phosphate fertilizers are given and future capacities are projected.
articles / manufacturing process of phosphorus fertilizers Phosphorus is a somewhat unique pollutant in that it is an essential element, has low solubility, and is not toxic itself, but may have detrimental effects on water quality at quite low concentrations.
DAP (Diammonium Phosphate): The fertilizer that quickly became the item of commerce because it had the highest concentration of phosphate and nitrogen at 18N – 46P 2 O 5 – 0K 2 O. MAP (Monoammonium Phosphate): This fertilizer is essentially the same as DAP, but it has a lower concentration of nitrogen at 11N – 52P 2 O 5 – 0K 2 O.

MONOAMMONIUM PHOSPHATE FERTILIZER PRODUCTION PROCESS The process for manufacturing monoammonium phosphate is relatively simple. In a common method, a onetoone ratio of ammonia (NH3) and phosphoric acid (H3PO4) in a pipecross reactor, where the reaction generates heat to evaporate water and solidify MAP is reacted and the resulting slurry of MAP .
Jan 10, 2017· Hubei and Guizhou Provinces were found to have the highest diammonium phosphate and monoammonium phosphate fertilizer yield and environmental effects, whereas Fujian, Jiangsu, Xinjiang, Henan, Sichuan, Shanxi and Hunan Provinces were small because of the distribution of phosphate rock mining and phosphate fertilizers production capacity.
Compound fertilizer can supply comprehensive nutrient for crops. The production process of compound fertilizer is to combine the main nutrient elements needed for crops (such as N, P, K and other trace elements) by chemical method, that is, gather the nitrogen fertilizer, phosphorus fertilizer, potash fertilizer and other chemicals together and make into particles which are suitable for farming.
