Mono ammonium
phosphate or Ammonium dihydrogen phosphate, NH4•H2PO4,
is formed when a solution of phosphoric acid is added to
ammonia until the solution is distinctly acid. It
crystallizes in quadratic prisms. Monoammonium phosphate is
often used in the blending of dry agricultural fertilizers.
It supplies soil with the elements nitrogen and phosphorus
in a form which is usable by plants. The compound is also a
component of the ABC powder in some dry chemical fire
extinguishers. This substance is also supplied in a jade
green or aquamarine crystal growing box kit for kids.
Uses:
Mono ammonium
phosphate (MAP) is used as
a fire-prevention agent for fabric, timber and paper, as
well as a fire-prevention coating, and dry powder for fire
extinguisher. For food grade it is mainly used as a
fermentation agent, nourishment, and so on. Used as a high
effective non-chloride N, P compound fertilizer in
agriculture. Its total nourishment (N=P2O5) is at 73%, and
may be used as a basic raw material for N, P and K compound
fertilizer.
Di ammonium hydrogen phosphate, or di ammonium phosphate, (NH4)2HPO4,
is formed by evaporating a solution of
phosphoric acid with excess of ammonia. It
crystallizes in large transparent prisms,
which melt on heating and decompose, leaving
a residue of metaphosphoric acid, (HPO3).
Di ammonium phosphate
(DAP) (chemical formula (NH4)2HPO4
) is one of a series of
water-soluble ammonium
phosphate salts which can be
produced when ammonia reacts
with phosphoric acid. Other
names include ammonium monohydrogen phosphate, and
ammonium phosphate dibasic.
Uses
Diammonium phosphate
(DAP) is used as a
fertilizer and a fire
retardant. When applied as
plant food,
DAP temporarily
increases the soil pH (more
basic), but over a long term
the treated ground becomes
more acidic than before upon
nitrification of the
ammonium. DAP is incompatible
with alkaline chemicals
because its ammonium ion is
more likely to convert to
ammonia in a high-pH
environment. As a flame
retardant, it lowers the
combustion temperature of
the material, decreases
maximum weight loss rates,
and causes an increase in
the production of residue or
char.
DAP is also
used as a
yeast nutrient in winemaking
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.
