FAQ

What are the physical and chemical properties of Calcium diiodide (CAS: 10102-68-8)?

Calcium diiodide (CAS: 10102-68-8) is a white crystalline solid with a molecular weight of 293.84 g/mol. It has a solubility of 0.17 g/L in water. It is relatively stable under normal conditions but reacts with strong acids to form hydrogen iodide. It is insoluble in ethanol and other organic solvents.

How is Calcium diiodide (CAS: 10102-68-8) typically synthesized?

Calcium diiodide can be synthesized by reacting calcium carbonate or calcium hydroxide with iodine. Another method involves the direct reaction of calcium chloride with iodine in the presence of a catalyst, such as iodine itself or a transition metal complex. The yield and selectivity depend on the reaction conditions and the choice of catalyst.

What industries use Calcium diiodide (CAS: 10102-68-8)?

Calcium diiodide is used in various industries, including pharmaceuticals for its use in the synthesis of certain drugs, semiconductors for doping materials, and as a reagent in analytical chemistry. It is also used in the production of sensors and as a stabilizer in the polymer industry.

What precautions should be taken when handling Calcium diiodide (CAS: 10102-68-8)?

When handling Calcium diiodide (CAS: 10102-68-8), wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. Store it in a cool, dry place away from direct sunlight. Use a fume hood when performing reactions to minimize exposure to fumes. In case of spill, sweep up the solid and dispose of it according to local regulations. Refer to the Safety Data Sheet (SDS) for detailed information on handling and storage.
