Beschreibung

Calcium acetate is a chemical compound which is calcium salt of acetic acid. It has the formula Ca(C2H3O2)2. Its standard name is calcium acetate, while calcium ethanoate is the systematic name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH3COO)2?H2O) is the common form.

Chemische Eigenschaften

Calcium acetate occurs as a white or almost white, odorless or almost odorless, hygroscopic powder.

Verwenden

Calcium Acetate is the calcium salt of acetic acid which functions as a sequestrant and mold control agent. it contains approximately 25% calcium. it is a white odorless powder which is readily soluble in water with a solubility of approximately 37 g in 100 g water at 0°c. its solubility decreases with increasing temperature, with a sol- ubility of approximately 29 g in 100 g of water at 100°c.

Verwenden

Calcium Acetate is the salt of acetic acid which is used as a preservative and sequestrant.

Definition

ChEBI: The calcium salt of acetic acid. It is used, commonly as a hydrate, to treat hyperphosphataemia (excess phosphate in the blood) in patients with kidney disease: the calcium ion combines with dietary phosphate to form (insoluble) calcium phosphate, which is excreted in the faeces.

Vorbereitung Methode

Calcium acetate can be prepared by soaking calcium carbonate (found in eggshells, or in common carbonate rocks such as lime stone or marble) in vinegar:
CaCO3 + 2CH3COOH → Ca(CH3COO)2 + H2O + CO2
Since both reagents would have been available pre-historically, the chemical would have been observable as crystals then.

synthetische

Produced by calcium hydroxide neutralization of acetic acid.

Pharmazeutische Anwendungen

Calcium acetate is used as a preservative in oral and topical formulations.
Therapeutically, parenteral calcium acetate acts as a source of calcium ions for hypocalcemia or electrolyte balance. Oral calcium acetate is used as a complexing agent for hyperphosphatemia in dialysis patients. Calcium acetate is also used in the food industry as a stabilizer, buffer and sequestrant.

Sicherheitsprofil

Poison by intravenous and intraperitoneal routes. Mutation data reported. See also CALCIUM COMPOUNDS. When heated to decomposition it emits acrid smoke and fumes.

Sicherheit(Safety)

Calcium acetate is used in oral and topical formulations. The pure form of calcium acetate is toxic by IP and IV routes.
LD50 (mouse, IP): 0.075 g/kg
LD50 (mouse, IV): 0.052 g/kg
LD50 (rat, oral): 4.28 g/kg

Veterinary Drugs and Treatments

Calcium acetate can be used for oral administration to treat hyperphosphatemia in patients with chronic renal failure. Secondary to its phosphorus binding efficiency and lower concentration of elemental calcium, calcium acetate is considered the most effective and having the lowest potential for causing hypercalcemia of the calcium-based phosphorus-binding agents. When compared to calcium carbonate, calcium acetate binds approximately twice as much phosphorus per gram of elemental calcium administered. Unlike calcium citrate, calcium acetate does not promote aluminum absorption.

Lager

Calcium acetate is stable although very hygroscopic, and so the monohydrate is the common form. It decomposes on heating (above 1608℃) to form calcium carbonate and acetone.
Store in well-closed airtight containers.

läuterung methode

Recrystallise it from water (3mL/g) by partial evaporation in a desiccator. [Beilstein 2 IV 113.]

Inkompatibilitäten

Calcium acetate is incompatible with strong oxidizing agents and moisture.

Regulatory Status

GRAS listed. Accepted for use as a food additive in Europe. Included in the FDA Inactive Ingredients Database (oral suspensions and tablets; topical emulsions, lotions, and creams). Included in nonparenteral medicines (oral tablets) licensed in the UK.
