Monoammonium Phosphate (MAP), is a white crystalline, chemical formula NH4H2PO4, heating will decompose into partial ammonium phosphate (NH4PO3), made available for the reaction of ammonia and phosphoric acid, mainly used as fertilizer and wood, paper, fabric fire retardant, drugs and ruminant feed additive. Also used as a fertilizer and wood, paper, fabric fire agent (such as a matchstick and the wick ember extinguish agent), in the food industry are also used as a leavening agent, dough regulator, yeast nutrients, brewing and fermentation aids nutrition fortifier.

 

As a fertilizer during the growing crop is the most appropriate application of ammonium phosphate, ammonium phosphate in acidic soil, and the seeds too close to possible adverse effects, in acidic soils than the calcium superphosphate, ammonium sulfate well in alkaline soil too superior to other fertilizers; should not be mixed with alkaline fertilizer, so as not to reduce fertility.

 

Production process: phosphoric acid and ammonium bicarbonate reaction of ammonium dihydrogen phosphate, potassium hydrogen phosphate and then generate and potassium chloride process. It is water, potassium chloride, ammonium bicarbonate proportionally feeding, a predetermined amount of phosphoric acid was then added, followed by sufficient stirring, pH was adjusted, and concentrated to 110 After heating, cooling and crystallization, centrifugal separation, and dried to obtain the product after KH2PO4, centrifugal separation of the resulting mother liquor is concentrated nitrogen, phosphorus, potassium and other multi-element compound fertilizer.
