Calcium Iodate is a source of iodine that is a white powder of slight
solubility in water, but greater solubility in water containing iodides
or amino acids. it is more stable than the iodide form. it is used as a
dough conditioner in bread and is a source of iodine in table salts.
제조 방법
This composition occurs
as a mineral “Lautarite (Calcium Iodate·Monohydrate). It
can be prepared by the reaction of iodic acid upon the
carbonate:
CaCO3 ＋2HIO3→Ca(IO3)2 ＋CO2＋H2O
The monohydrate formed has limited solubility in
water and can be separated by filtration.The slurry can be evaporated to increase the yield.
Safety Profile
A nuisance dust.
Purification Methods
Crystallise it from water (100mL/g at 100o and 100mL/0.1g at 0o). [Bahl & Singh J Indian Chem Soc 17 397 1940.]
