use:
Tartaric acid is widely used as an acidifier in beverages and other foods,
Tartaric acid is also used in certain developing and fixing operations in the photographic industry,
Tartaric acid can complex with a variety of metal ions and can be used as a cleaning agent and polishing agent for metal surfaces.
Tartaric acid crystals have piezoelectric properties and can be used in the electronics industry.
Tartaric acid is used as a chromatographic analysis reagent and masking agent.
Production method Tartaric acid mainly exists in the fruits of various plants in the form of potassium salt, and a small amount also exists in the free state. D-tartaric acid is commonly produced in industry by fermentation of glucose; the racemate can be produced by oxidizing fumaric acid with potassium permanganate; the mesoform can be produced by oxidizing maleic acid with Chemicalbook potassium permanganate. ;L-alcolic acid can be obtained by splitting the racemate. In the field of practical application of tartaric acid, dextrorotatory tartaric acid or its double salt is mainly used. Tartar, a by-product of grape brewing, is currently the main raw material for the actual production of tartaric acid, and the tartaric acid produced is all dextrorotatory.
