Tartaric Acid

Description:

Tartaric acid is a white crystalline diprotic organic acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds; is commonly combined with baking soda to function as a leavening agent in recipes,and is one of the main acids found in . It is added to other foods to give a sour taste, and is used as an antioxidant. Salts of

tartaric acid are known as tartrates. It is a dihydroxyl derivative of succinic acid.

• L(+)-Tartaric acid is widely used as acidulant in beverage,and other foods, such as soft drinks, candy, bread and some colloidal sweetmeats.
• Its optical activity, L(+)-Tartaric acid is used as chemical resolving agent to resolve DL-amino-butanol, an intermediate for antitubercular drug. And it is used as chiral pool to synthesize tartrate derivatives.
• Its acidity, it is used as catalyst in the resin finishing of polyester fabric or pH value regulator in oryzanol production.
• Its complexation, L(+)-Tartaric acid is used in electroplating, sulfur removal and acid pickling. It is also used as complexing agent, screening agent or chelating agent in chemical analysis and pharmaceutical inspection, or as resist agent in dyeing.
• Its reduction, it is used as reductive agent in manufacturing mirror chemically or imaging agent in photography. It can also complex with metal ion and can be used as cleaning agent or polishing agent of metal surface.
