About L-Tartaric Acid E334-87-69-4
is widely present in fruits, especially grapes. E334 is the cheapest of the optical activity of tartaric acid, E334 is often referred to as "natural tartaric acid." Industry, E334-87-69-4s are still the main or even sole source of natural products. Wine industry by-products of tartar, acid treatment can be obtained by E334-87-69-4. Italy is the worlds E334-87-69-4s largest producer of this wine made ​​with the size of the country are not unrelated.
E334-87-69-4 maximum use of the beverage additive. Then the drug industry raw materials. In modern organic synthesis is very important chiral ligands and hand temper, E334-87-69-4 used to produce many well-known chiral catalysts, and E334 as a chiral source to synthesize complex natural product molecules. E334-87-69-4 is also an antioxidant, has been applied in the food industry.
E334-87-69-4 usage:
E334-87-69-4 is widely used as food, beverages and other sour agent. With its optical activity, E334-87-69-4 as a chemical resolving agent to resolve DL-amino-butanol, anti-TB drug intermediates. E334-87-69-4 is used for synthesis of tartaric acid derivatives as chiral pool. With its acidity, E334-87-69-4 is used as a catalyst in the resin finishing of polyester fabric or a pH regulator oryzanol production. With its complex, E334-87-69-4 is used in electroplating, desulfurization, acid.
