About L-Tartaric Acid:
L-Tartaric Acid is widely present in fruits, especially grapes. L-Tartaric Acid is the cheapest of the optical activity of tartaric acid, L-Tartaric Acid is often referred to as "natural tartaric acid." Industry, L-Tartaric Acid are still the main or even sole source of natural products. Wine industry by-products of tartar, acid treatment can be obtained by L-Tartaric Acid. Italy is the worlds L-Tartaric Acid largest producer of this wine made with the size of the country are not unrelated.
L-Tartaric Acid maximum use of the beverage additive. Then the drug industry raw materials. In modern organic synthesis is very important chiral ligands and hand temper, L-Tartaric Acid used to produce many well-known chiral catalysts, and E334 as a chiral source to synthesize complex natural product molecules. L-Tartaric Acid is also an antioxidant, has been applied in the food industry.
L-Tartaric Acid usage:
L-Tartaric Acid is widely used as food, beverages and other sour agent. With its optical activity, L-Tartaric Acid as a chemical resolving agent to resolve DL-amino-butanol, anti-TB drug intermediates. L-Tartaric Acid is used for synthesis of tartaric acid derivatives as chiral pool. With its acidity, L-Tartaric Acid is used as a catalyst in the resin finishing of polyester fabric or a pH regulator oryzanol production. With its complex, L-Tartaric Acid is used in electroplating, desulfurization, acid.
