Calcium iodate Chemical Properties,Usage,Production

Chemical Properties

Colorless Orthorhombi crystal or white crystal. Odorless. Boiling point: 783 ℃. Relative density: 2.55. Soluble in nitric acid, slightly soluble in water. Six crystal water will be dehydrated at 40 ° C and it will become anhydrous.

Uses

Used as: 

  • Iodine additives for premix in feed industry:  
  • Quality enhancers, preservatives in food industry; 
  • Mouthwash preparation, iodine substitutes and nutritional supplements trace elements and deodorant in pharmaceutical industry;
  • Wheat flour treatment;  
  • Dough conditioner; 
  • Quick-acting oxidant to the dough when making bread by being added to wheat flour.

Preparation

  • Direct synthesis process
Pass through the chlorine into the mixture of iodine and water at 10-15 ° C until the iodine is completely transformed into iodic acid, and then add calcium hydroxide to adjust the pH up to 7. Wash the formed precipitate and dry it at 110 ° C to obtain the finished product.
  • Complex decomposition process 
Put potassium iodate into a reactor containing distilled water, stir and add calcium nitrate solution slowly to react to form calcium iodate and potassium nitrate reaction solution, then filter off to remove potassium nitrate. Then add arsenic removal agent and heavy metal agent to purify the solution,  and filter off to remove the arsenic and heavy metals and other impurities.  Then get the filtrate to be concentrate by evaporation, cooled and crystallized, centrifugated, dried,  and we can obtain the finished food calcium iodate. Ca (NO3) 2 • 4H2O + 2KIO3 + 2H2O → Ca (IO3) 2 • 6H2O + 2KNO3

Water solubility (g/100ml)

Grams that dissolve in per 100 ml of water at different temperatures (° C):
9×10-2/30℃;0.24g/20℃;0.38g/30℃;0.52g/40℃
0.65g/60℃;0.66g/80℃;0.67g/90℃

Content analysis

Weigh about 600mg of sample accurately, and then dissolve them in the mixed solution of 10mL of 70% perchloric acid and 10ml of water. Heat it to help dissolution If necessary, and dilute with water to 250.0ml. Take 50.0ml of this solution and put it into a 250ml Erlenmeyer flask, add 1ml of 70% perchloric acid and 5g of potassium iodide, stoppered, shake gently and then leave it to stand still for 5min. Then titrate with 0.1mol / L sodium thiosulfate, and then add at a small amount of starch test solution (TS-235 when nearing the end. 0.1mol / L sodium thiosulfate per mL equals to 3.398mg of calcium iodate [Ca (IO3)2·H2O].

Toxicity

ADI:  Not allowed to use (FAO / WHO, 2001).
GR.AS(FDA，§184.1206，2000)

Uses

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.

Uses

Calcium iodate (also called Lautarite) is used as an oxidant added to lotions and ointments as an antiseptic and deodorant. It is also used in the food industry in animal feed, and the manufacture of disinfectants.The forms of iodine most commonly used in animal feed are calcium iodate, ethylenediamine dihydriodide (EDDI), and potassium iodide. Calcium iodate is usually the most stable source of iodine. All three major sources of iodine (calcium iodate, EDDI, and potassium iodide) are roughly equivalent in biological availability.

Preparation

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.

Flammability and Explosibility

Non flammable

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.]
