It has the formula Ca(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)<sub>2</sub>. 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 mono[[hydrate]] (Ca(CH<sub>3</sub>COO)<sub>2</sub>.H<sub>2</sub>O, 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 Canned Heat|Sterno]].<ref>[http://jchemed.chem.wisc.edu/jcesoft/CCA/CCA3/MAIN/CANHEAT/PAGE1.HTM "Canned Heat" at Journal of Chemical Education "Chemistry comes alive!"]</ref> 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]]. ==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]].<ref>{{cite journal | title = Losses Incurred in the Preparation of Acetone by the Distillation of Acetate of Lime. | author = Leo Frank Goodwin and Edward Tyghe Sterne | journal = Industrial & Engineering Chemistry | volume = 12 | issue = 3 | year = 1920 | pages = 240–243 | doi = 10.1021/ie50123a012 }} </ref> <ref>{{cite journal | title = Distillation of Acetate of Lime. | author = E.

Calcium acetate binds phosphate in the diet to lower blood phosphate levels. Side effects of this treatment include upset stomach. Calcium acetate is a [[food additive]], mainly in candy products. ==References== <references/> {{inorganic-compound-stub}} [[Category:Acetates]] [[Category:Calcium compounds]] [[Category:Phosphate binders]] [[Category:Carboxylic acids]] [[ar:خلات كالسيوم]] [[de:Calciumacetat]] [[es:Acetato de calcio]] [[fr:Acétate de calcium]] [[it:Acetato di calcio idrato]] [[hu:Kalcium-acetát]] [[nl:Calciumacetaat]] [[ja:酢酸カルシウム]] [[pl:Octan wapnia]]
