Anwendungen
VerwendenCalcium 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.
Darstellung
synthetischeThis 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.
