Ammonium Di-hydrogen Orthophosphate, Ammonium Phosphate Mono-basic or Mono Ammonium Phosphate (MAP)


H3PO4 + NH3 = (NH4)H2PO4

Grades We Manufacture :

Mono Ammonium Phosphate Industrial Grade
Mono Ammonium Phosphate Pure Grade

Mono ammonium phosphate is formed when ammonia gas is added to solution of phosphoric acid and reacted until the desired PH is obtained and solution gets distinctly acidic. End product is in the form of tetragonal prisms.


  Mono ammonium phosphate is used as a baking powder with sodium bicarbonate
  Widely used in fireproofing of paper, wood, fiberboard
  Mono ammonium phosphate is mixed with ammonium sulfate and resultant is used in ABC dry chemical fire extinguishers.
  MAP is also used in fermentation of yeast
  MAP provides a rich source of phosphate and nitrogen usable by plants helping their growth.
  It contains relatively less PH than di ammonium phosphate which suits it best for fertilizer use, reducing the seed damage.
