The chemical compound calcium acetate is the calcium salt of acetic acid. It has the formula Ca(C2H3O2)2. Calcium acetate standard name is calcium acetate, while Calcium acetate is the systematic IUPAC name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH3COO)2.H2O, CAS [5743-26-0]) is the common form.
If an alcohol is added to a saturated solution of calcium acetate, a semisolid, flammable gel forms that is much like "canned heat" products such as Sterno.[1] Chemistry teachers often prepare "California Snowballs", a mixture of calcium acetate solution and ethanol. The resulting gel is whitish in color, and can be formed to resemble a snowball.
Calclacite is a name for calcium acetate chloride pentahydrate, which is treated as mineral species but possess anthropogenic origin.Calcium Acetate, (CH3COO)2Ca (E263), in food industry is used as a betterment inhibitor for certain fungus. It is used in bread and other baked foods to prevent rope creation and to extend the preserved life.
Calcium Acetate is available as a white powder or agglomerate. Both versions are chemically identical, and differ only in physical form.
Calcium Acetate is an approved and certified product, and complies to the indian Food Chemical Codex V.
[edit]History
Because it is inexpensive, calcium acetate was once a common starting material for the synthesis of acetone before the development of the cumene process.
Calcium Acetate can be prepared by soaking eggshells in vinegar. Since both reagents would have been available pre-historically, the chemical would have been observable as crystals then.
Uses
In kidney disease, blood levels of phosphate may rise (called hyperphosphatemia) leading to bone problems. Calcium acetate binds phosphate in the diet to lower blood phosphate levels. Side effects of this treatment include upset stomach.
Calcium acetate is used as a food additive, as a stabilizer, buffer and sequestrant, mainly in candy products. It also neutralizes fluoride in water.
