Calcium acetate - C4H6CaO4

What is Calcium acetate?

C4H6CaO4 is a calcium salt of acetic acid with a chemical name Calcium acetate. It is also called Acetate of lime or Calcium ethanoate or Calcium diacetate. It is widely used as a hydrate in treating hyperphosphataemia and functions as a chelator.

It is hygroscopic in its anhydrous form and monohydrate in the common form. A mineral such as calcium is required for many cellular functions such as nerve impulse transmission, cardiac function, cell membrane permeability, muscle contraction, and bone formation. Calcium acetate is taken orally to treat or prevent calcium deficiency as well as to treat hyperphosphatemia as it has excellent phosphate-binding properties.

C4H6CaO4 Uses (Calcium acetate)

  • Calcium acetate is used as a food additive.
  • Used as a corrosion inhibitor.
  • Used is the manufacturing of lubricants.
  • Used as a stabilizer in resins.
  • Used in bakery goods as an anti mold agent.
  • Used in gelatin as thickener.
  • Used as an esterification catalyst.
  • Used in the making of agricultural products.
  • Used as a filler and stabilizing agent.

Calcium acetate Production

Calcium ethanoate can be obtained by soaking hydrated lime or calcium carbonate in vinegar. The reaction is as follows:

CaCO3(s) + 2CH3COOH(aq) → Ca(CH3COO)2(aq) + H2O(l) + CO2(g)

Ca(OH)2(s) + 2CH3COOH(aq) → Ca(CH3COO)2(aq) + 2H2O(l)

Health hazards

Acetate of lime is verified and considered to be of low concern based on the experiments conducted and data gathered. It is combustible under fixed conditions.
