| [SELL] L(+) tartaric acid [2008-02-18] |
| L(+)-tartaric acid (BP98)
Properties: White crystals or
white powder. It is odorless,
acidy and of air stability.
Product name: L(+)-tartaric acid
(BP98)
Chemical Name : L(+)-2,3-
dihydroxy butanedioic acid
Molecular Formula: C4H6O6
Function and uses: L(+)-Tartaric
acid is widely used as acidulant
in beverage and other foods, such
as soft drinks, candy, bread and
some colloidal sweetmeats. With
its optical activity, L(+)-
Tartaric acid is used as chemical
resolving agent. With its
acidity, it is used as catalyst
in the resin finishing of
polyester fabric or pH value
regulator in oryzanol production.
With its complexation, L(+)-
Tartaric acid is used in
electroplating, sulfur removal
and acid pickling. It is also
used as complexing agent,
screening agent or chelating
agent in chemical analysis and
pharmaceutical inspection, or as
resist agent in dyeing. With its
reduction, it is used as
reductive agent in manufacturing
mirror chemically or imaging
agent in photography. It can also
complex with metal ion and can be
used as cleaning agent or
polishing agent of metal surface.
