Both are made by reacting tartaric acid with the appropriate alcohol, ethanol or n-butanol. In the reaction the Hydrogen of the COOH acid group is replaced with an ethyl group diethyl tartarate or butyl group dibutyl tartarate. These esters are used in manufacturing lacquer and in dyeing textiles. This website uses cookies so that we can provide you with the best user experience possible.

Tartaric Acid Tartaric acid is a white crystalline diprotic organic acid. Description Description In general, where biological molecules have optical isomers, only one of the isomers or forms will be active biologically.
Applications Tartaric acid is found in cream of tartar, which is used in making candies and frostings for cakes. Error file size too large The uploaded file extension not valid. Which product are you interested in? Visual Text. Link Text. Open link in a new tab.
No search term specified. Even though there is a product available on the market with a similar molecular structure but of completely different origin, current EU legislation, with the sole exception of wine legislation, does not differentiate at all between the natural and the synthetic form of tartaric acid.
This gives rise to an abnormal situation in terms of product traceability, proper information for consumers and competition in the food additive market, given that the synthetic product is clearly much cheaper. Can the Commission say whether it intends to differentiate between the two products also through appropriate changes to the Customs Code?
Industrial uses for tartaric acid include within the gold and silver plating process, cleaning and polishing metals, tanning leather and making blue ink for blueprints.
Tartaric acid is also an ingredient in Rochelle Salt, which reacts with silver nitrate to create the silvering on mirrors. Rochelle Salt is also a laxative, according to The Chemical Company.
Ester derivatives of tartaric acid can dye fabrics. By-products obtained from wine manufacturers for the basis for the commercial production of tartaric acid. The sediments and other waste products that result from the fermentation of wine are heated with calcium hydroxide, a base. This causes calcium tartrate to form a precipitate, which is then treated with sulfuric acid to produce a combination of calcium sulfate and tartaric acid. After separation, the tartaric acid is then purified for commercial use.
