Tartaric acid is a kind of carboxylic acid, which can be found in many plants, such as grapes and tamarind, it is one of the main organic acids in the grape wine. As antioxidant added in food, it can make the food have sour taste. Its most important application is beverage additives. It is raw materials in the medicine industry. In the mirror industry, tartaric acid is an important auxiliary agent and reducing agent, it can control the forming speed of silver mirror and get a very uniform coating.
It can be used as antioxidant synergist, retarder, tanning agent, chelating agent and medicine agent. It is widely used in medicine, food, leather, textile and other industries. Its solubility in water is low at low temperature and insoluble calcium salt is easy to be generated.

L(+)-Tartaric acid is widely used as acidulant in beverage,and other foods, such as soft drinks, wine, candy, bread and some colloidal sweetmeats. With its optical activity, L(+)-Tartaric acid is used as chemical resolving agent, an intermediate for antitubercular drug. And it is used as chiral pool to synthesize tartrate derivatives. With its acidity, it is used as catalyst in the resin finishing of polyester fabric or pH value regulator in oryzanol production. With 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. With 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. |
