Chemische Eigenschaften
Tartaric acid occurs as colorless monoclinic crystals, or a white or almost white crystalline powder. It is odorless, with an extremely tart taste. L-(+)-Tartaric Acid is a naturally occurring chemical compound found in berries, grapes and various wines. It provides antioxidant properties and contributes to the sour taste within these products.
Verwenden
L(+)-Tartaric acid is widely utilized in pharmaceutical industries. It is used in soft drinks, confectionaries, food products, gelatin desserts and as a buffering agent. It forms a compound, TiCl2(O-i-Pr)2 with Diels-Alder catalyst and acta as a chelate agent in metal industries. Owing to its efficient chelating property towards metal ions, it is used in farming and metal industries for complexing micronutrients and for cleaning metal surfaces, respectively.
Definition
ChEBI: L-tartaric acid is a tetraric acid that is butanedioic acid substituted by hydroxy groups at positions 2 and 3. It is a conjugate acid of a L-tartrate(1-). It is an enantiomer of a D-tartaric acid.
Vorbereitung Methode
Tartaric acid occurs naturally in many fruits as the free acid or in
combination with calcium, magnesium, and potassium.
Commercially, L-(＋)-tartaric acid is manufactured from potassium
tartrate (cream of tartar), a by-product of wine making.
Potassium tartrate is treated with hydrochloric acid, followed by the
addition of a calcium salt to produce insoluble calcium tartrate.
This precipitate is then removed by filtration and reacted with 70%
sulfuric acid to yield tartaric acid and calcium sulfate.
Allgemeine Beschreibung
L(+)-Tartaric acid belongs to the group of carboxylic acids, and is abundantly found in grapes and wine. It is widely used in drugs, food, and beverage industry.
Pharmazeutische Anwendungen
Tartaric acid is used in beverages, confectionery, food products, and
pharmaceutical formulations as an acidulant. It may also be used as
a sequestering agent and as an antioxidant synergist. In pharmaceutical
formulations, it is widely used in combination with
bicarbonates, as the acid component of effervescent granules,
powders, and tablets.
Tartaric acid is also used to form molecular compounds (salts
and cocrystals) with active pharmaceutical ingredients to improve
physicochemical properties such as dissolution rate and solubility.
Sicherheitsprofil
Moderately toxic by intravenous route. Mildly toxic by ingestion. Reaction with silver produces the unstable silver tartrate. When heated to decomposition it emits acrid smoke and irritating fumes.
Sicherheit(Safety)
L(+)-Tartaric acid is widely used in food products and oral, topical, and parenteral pharmaceutical formulations. It is generally regarded as a nontoxic and nonirritant material; however, strong tartaric acid solutions are mildly irritant and if ingested undiluted may cause gastroenteritis.
An acceptable daily intake for L-(＋)-tartaric acid has not been set by the WHO, although an acceptable daily intake of up to 30 mg/kg body-weight for monosodium L-(＋)-tartrate has been established. LD50 (mouse, IV): 0.49 g/kg.
Lager
The bulk material is stable and should be stored in a well-closed
container in a cool, dry place.
Inkompatibilitäten
Tartaric acid is incompatible with silver and reacts with metal
carbonates and bicarbonates (a property exploited in effervescent
preparations).
