Diammonium phosphate,
DAP
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.Â
Molecular formula: (NH4)2HPO4
Molecular weight: **1.***8
CAS No: ********0
EINECS: ********8
PH: 7.**8.2(*0g/L, *5℃)
Appearance: White granular crystal or powder
Purity: *8%
Properties: Colorless clarity rhombic crystal or
white powder and the relative density is 1.**9g/cm3, melting point
is **5°C (decompounds at **5 centigrade), easy to dissolve in water
and not dissolve in alcohol, acetone and ammonia. The PH value of
1% water solution is 8.0. It will lose gradually ammonia to become
ammonium dihydrogen phosphate in the air. React with ammonia and
form triammonium phosphate.
Applications:Â
It can be used for nitrogen and phosphrous supply to all kinds of
plants especially in the regions with less rain. It is the base
fertilizer for multi-element compound fertilizer and BB fertilizer
production.
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 7.5–8. The typical
formulation is ******0 NPK.
DAP can be used as a fire retardant. It is the largest component of
some popular commercial firefighting products.Â
DAP is also used as a yeast nutrient in wine making and brewing
mead; as an additive in some brands of cigarettes purportedly as a
nicotine enhancer; to prevent afterglow in matches, in purifying
sugar; as a Flux for soldering tin, copper, zinc and brass; and to
control precipitation of alkali-soluble and acid-insoluble
colloidal dyes on wool.Â
Package and storage: Plastic-woven sack with polythene inner bag,
net weight per bag is *5kg, *0kg and **0kg. Keep in dry and windy
conditions.
