Description

Diammonium phosphate (DAP) (chemical formula (NH4)2HPO4, IUPAC name diammonium hydrogen phosphate) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. DAP is used as a fertilizer. When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment. The average pH in solution is 7.*8. The typical formulation is ******0 (*8% N, *6% P2O5, 0% K2O)

Other Uses:

• DAP can be used as a fire retardant.
• As a yeast nutrient in winemaking.
• Mead brewing
• As a nicotine enhancer in Cigarettes.
• In purifying sugar
• As a Flux for soldering Tin, Copper, Brass and Zinc
