Product Description

Ammonium Dihydrogen Phosphate With Cas 7722-76-1

Ammonium dihydrogen phosphate, chemicals, also known as monoammonium phosphate, is a kind of white crystal, chemical formula is NH4H2PO4, heating will decompose into partial ammonium phosphate (NH4PO3), can be used after the reaction, ammonia and phosphoric acid is mainly used as fertilizer and wood, paper, fabric fire prevention agent, also used in pharmaceutical and ruminant feed additives.

Use
Fire retardants (such as those used to extinguish the embers of match stalks and candle cores) used for phosphorus fertilizers and wood, paper and fabric, are also used to make medicines. It is also used as a feed additive for ruminant animals.
[preparation or source]
It is made by acid and alkali reaction of phosphoric acid and ammonia.

Stable in the air. When the temperature is higher than the melting point, ammonia and water are decomposed and lost, forming a mixture of ammonium bisphosphate and phosphoric acid. A small number of decomposition at 100 ℃.
As the ammonium phosphate fertilizer is used during the period of crop growth is the most appropriate, acidic ammonium phosphate in the soil, and seeds possible adverse effects of too close to it in the acid soil is better than, calcium, ammonium sulfate, in alkaline soil is superior than other fertilizer; Should not be mixed with alkaline fertilizer, so as not to reduce fertilizer efficiency. If lime is to be used in acidic soils in the south, monoammonium phosphate should be applied several days apart.
