Calcium acetate monohydrate (Ca(OOCCH3)2•H2O)-Powder

Characteristic




Calcium acetate is a chemical compound which is a calcium salt of acetic acid. It has the formula Ca(C2H3O2)2. Its standard name is calcium acetate, while calcium ethanoate is the systematic name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH3COO)2•H2O) is the common form.

Application




Calcium acetate monohydrate is used to precipitate oxalates in solution. It is used to control the phosphate levels in blood, thereby controlling the bone problems. It is also involved in the neutralization of fluoride in water. Further, it is used as a food additive mainly in candy products. In addition to this, it serves as a stabilizer, buffer and sequestrant.
