Its properties are similar to related salts such as calcium chloride. It is used for photography. It is also used as a source of iodine in cat food.

Calcium iodide is a ionic compound with chemical formula of CaI2 and molar mass of 293.88 g/mol. Let's explore the importance of calcium iodide.

The use of calcium iodide:

Synthetic applications

Commercial applications

Here, let's provide a detailed introduction to the various chemical and physical properties of calcium iodide.

Synthetic applications

A catalyst for the synthesis of trisubstituted cyclic carbonates using biologically derived epoxides and carbon dioxide as raw materials.

Under visible light irradiation, β- Ketone esters are also catalyzed by CaI2 to convert into tartrate and hydroxymalonate.

Oxycarboxylate ester undergoes photo oxidation internal esterification reaction under the catalysis of calcium iodide.

Except for Me3SiCN, aromatic carbonyl groups generate cyanide derivatives in the presence of CaI2.

By utilizing the catalytic activity of CaI2, epoxides can be converted into environmentally friendly cyclic carbonates.

The use of CaI2 as a catalyst also provides efficient green protection for the hydrolysis of amino esters.

Industrial applications

CaI2 is a highly water-soluble deliquescent salt.

As a rich source of iodine, CaI2 is commercially available as cat food.

Although CaI2 is unstable under normal conditions, it reacts with carbon dioxide to form carbonates, releasing iodine from the gas.

CaI2 is used for photography, but its purpose is unknown.

Conclusion

Calcium iodide is a colorless ionic chemical substance with properties similar to calcium chloride. It is widely used as a green catalyst and an important reagent for organic synthesis and catalytic reactions. This compound is soluble in acetone and ethanol. It has a diamond shaped structure and octahedral coordination geometry.
