APPLICATIONS
|
Hypophosphorous
acid is the phosphorus oxo acid or hydroxy phosphine oxide,
with monobasic character. The term phosphinic acid is
for the descriptive presentation of derivatives or salts
which hydrogen atoms bound to
phosphorus are replaced by organic groups, called phosphinates. The term hypophosphite
is also used for any salt, ester or anion derived
from the name of hypophosphorous acid.
Hypophosphorous
acid is a low-melting point compound soluble in water.
It is a powerful reducing agent. Hypophosphorous
acid and its sodium salt (sodium hypophosphite)
are used as powerful reducing agents
in various field. (Hypophosphorous acid has an advantage of easy
implementation in solution.) They are used in:
- Pharmaceutic aid as
antioxidant
- Retrieval of
non-ferrous
- Ingredient of
electroless plating solutions.
- Water treatment agent
- Meat preservative.
- Prevent the discoloration of polymers
- Production
of chemicals
Sodium
Phenylphosphinate is utilized as a color, light and
heat stabilizer for polymers especially polyamides. It is a powerful reducing agent reacting rapidly with
oxidizing agents.
