Calcium Gluconate is extensively used
in the treatment of Calcium deficiency, both for oral
and parenteral administration. It is also used as an
oral antidote for fluorine and onalic acid poisoning
and as a substitute for fruit acids in the manufacture
of fruit jellies and baking powders and in the preparation
of homogeneous pastes like dentifrices and metal polishes;
ferrous gluconate which can be readily made from Calcium
Gluconate is used in the treatment iron deficiency and
in tonic compositions. Aluminium Gluconate has potential
use as a tanning agent.
Process
Calcium Gluconate is produced by the
electrolytic oxidation of Glucose dissolved in sodium
bromide solution used as electrolyte in a cell having
graphite electrodes. Gluconic acid formed is neutralised
by the suspended Calcium Carbonate present in the electrolyte.
Calcium Gluconate formed in the electrolyte is recovered
by cooling the the mother liquor obtained after recovery
of the product is continuously reused in further batches.
