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


Grades We Manufacture :
• Mono Ammonium Phosphate (Industrial Grade)
• Mono Ammonium Phosphate (LR/Pure Grade)

Formulation :
H3PO4 + NH3 = (NH4)H2PO4

Mono ammonium phosphate is formed when ammonia gas is added tosolution 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.

Application :
• 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
