The chemical compound calcium acetate is the calcium salt of acetic acid. It has the formula Ca(C₂H₃O₂)₂. Its standard name is calcium acetate, while calcium ethanoate 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. Grain alcohol redirects here. ... A sampling of snowballs. ...

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.^{[2] [3]} For other uses, see Acetone (disambiguation). ... Cumene process is an industrial process of producing phenol (C6H5-OH) and acetone (CH3-CO-CH3) from benzene (C6H6) and propene (C3H6). ...

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. See the article on the kidney for the anatomy and function of healthy kidneys and a list of diseases involving the kidney. ... A phosphate, in inorganic chemistry, is a salt of phosphoric acid. ... Hyperphosphatemia is an electrolyte disturbance in which there is an abnormally elevated level of phosphate in the blood. ...

Calcium acetate is a food additive, mainly in candy products, or as a preservative in bread products. Food additives are substances added to food to preserve flavor or improve its taste and appearance. ...
