5K
3O
7. It is a white, slightly hygroscopic crystalline powder. It is odorless with a saline taste.
As a food additive, potassium citrate is used to regulate acidity and is known as E number E332. Medicinally, it may be used to control kidney stones derived from either uric acid or cystine.
Chemische Eigenschaften
Colorless or white crystals or powder;
cooling, saline taste; odorless; deliquescent. Soluble
in water and glycerol; almost insoluble in alcohol.
Verwenden
potassium citrate is it acts as a buffer, maintaining product pH constant, a pH adjuster and a product stabilizer. This is a potassium salt.
Definition
ChEBI: The anhydrous form of the tripotassium salt of citric acid.
Vorbereitung Methode
Potassium citrate is produced by adding potassium bicarbonate or potassium carbonate to a solution of citric acid until effervescence ceases, filtering the solution and evaporating to granulation.
Industrielle Verwendung
Potassium citrate is used in the United Kingdom as an over-the-counter drug for the relief from discomfort
experienced in mild urinary-tract infections by increasing the urinary pH. It should be not given to men if
they experience pain in the kidney area (risk of kidney stones) or if blood or pus is present in the urine. Also,
patients with raised blood pressure or diabetes should avoid taking potassium citrate without consultation
with their general practitioner (GP). Caution is generally advised to patients with renal impairment, cardiac
problems and the elderly [3a].
Sicherheitsprofil
Poison by intravenous
route. When heated to decomposition it
emits toxic fumes of K2O.
Vorsichtsmaßnahmen
Potassium citrate is usually administered by mouth in dilute aqueous solution. This is because of its somewhat caustic effect on the stomach lining, and the potential for other mild health hazards.
In states where non-prescription potassium citrate is legal, the maximum allowable over-the-counter (OTC) dose for elemental potassium is regulated by the FDA to be no more than 100 mg (approximately 3 % of the daily allowance ) . Pure potassium citrate contains 38.28 % potassium.
