Pure Calcium Acetate

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.

Calcium acetate is used as a food additive, as a stabilizer, buffer and sequestrant, mainly in candy products under the number E263.

Tofu is traditionally obtained by coagulating soy milk with calcium sulfate. Calcium acetate has been found to be a better alternative; being soluble, it requires less skill and a smaller amount.

Because it is inexpensive, calcium acetate was once a common starting material for the synthesis of acetone before the development of the cumene process:

Ca(CH3COO)2 CaCO3(s) + (CH3)2CO(v)

A saturated solution of calcium acetate in alcohol forms a semisolid, flammable gel that is much like "canned heat" products such as Sterno.[6] Chemistry teachers often prepare "California Snowballs", a mixture of calcium acetate solution and ethanol.[7] The resulting gel is whitish in color, and can be formed to resemble a snowball.
