DESCRIPTION: Â
Gluconic Acid *0% is composed of an equilibrium
between the free acid and the two lactones. This equilibrium is
affected by the mixture's concentration and temperature. A high
concentration of the delta-lactone will favor the equilibrium to
shift to the formation of gamma-lactone and vice versa. A low
temperature favors formation of glucono-delta-lactone while high
temperatures will increase formation of glucono-gamma-lactone.
Under normal conditions, PMP Gluconic Acid *0% exhibits a stable
equilibrium contributing to its clear to light yellow color with
low level corrosiveness and toxicity.
Â
APPLICATION:
Gluconic acid has
versatile properties through being a polyhydroxycarboxylic acid,
with both hydroxyl and carboxyl groups which can
react.
Concentrated
solutions of gluconic acid contain some lactone (GDL), the neutral
cyclic ester, which is less soluble in the cold and possesses no
actual acid properties. About 5 % of GdL are present in the *0 %
gluconic acid solution at room
temperature.
The outstanding
property of gluconic acid is its excellent chelating power,
especially in alkaline and concentrated alkaline solutions. In this
respect, it surpasses all other chelating agents, such as EDTA, NTA
and related compounds. Calcium, iron, copper, aluminum and other
heavy metals are firmly chelated in alkaline solution and masked in
such a way that their interferences are
eliminated.
Gluconic acid is
stable at the boiling point even of concentrated alkaline
solutions. However, it is easily and totally degraded in waste
water treatment plants (*8% after 2 days).
