Chemistry & industry
Uses & manufacturing
General Manufacturing InformationPerchloric acid, calcium salt (2:1): ACTIVE
Applications
DescriptionThe anhydrate is a white to yellow crystalline solid with a density of 2.651 g/cm3. Contact with this salt will irritate the eyes, skin and mucus membranes. If ingested, it is toxic in sufficient quantities. When formed from an aqueous solution, the tetrahydrate is obtained. Calcium perchlorate tetrahydrate has the formula Ca(ClO4)2·4H2O and the CAS number 15627-86-8. Its molecular weight is 311.04 g/mol and its density is 2.651 g/cm3. Its solubility in water is 188 g/ 100 ml at 20°C.
UsesCalcium perchlorate hydrate is used as a pharmaceutical intermediate.
General DescriptionCalcium perchlorate is a white to yellow crystalline solid. Density 2.651 g / cm3. Contact may irritate skin, eyes, and mucous membranes. May be toxic by ingestion.
Preparation methods
PreparationCalcium perchlorate can be prepared by reacting calcium carbonate with a solution of perchloric acid: CaCO3＋ HClO4→Ca(ClO4)2＋ CO2 This salt can also be prepared by an electrochemical method in water whereby calcium perchlorate is formed from calcium chlorate in which a platinum anode and a rotating stainless steel cathode is employed.
