Manufature Di Ammonium Phosphate DAP 18-46-0

Ammonium phosphates include mono- and diammonium orthophosphates and ammonium polyphosphates. As discussed below, these are made directly by reaction anhydrous ammonia with orthophosphoric acid or super phosphoric acid. Both are dry crystalline materials with good handling properties.

Di ammonium phosphate appears as colorless transparent monoclinic crystal or white powder, being soluble in water, insoluble in alcohol, acetone and ammonia.
