It has been used in the production of effervescent salts, in combination with citric acid, in order to improve the taste of oral medications. The potassium antimonyl derivative of the acid known as tartar emetic is included, in small doses, in cough syrup as an expectorant. Melting range 200 - 206o with decomposition when heated rapidly in a sealed capillarytube substances N potassium permanganate while keeping the solution at 20o . The colour of the solution does not disappear within 3 min. METHOD OF ASSAY Weigh accurately about 2 g of the dried sample, dissolve it in 40 ml of water, add phenolphthalein TS, and titrate with 1 N sodium hydroxide. Each ml of 1 N sodium hydroxide is equivalent to 75.04 mg of C4H6O6. Chemical Properties Tartaric acid, HOOC(CHOH)2COOH, is a water- and alcohol-soluble colorless crystalline solid with an acid taste and a melting temperature of 170°C (338 OF). It is also known as dihydroxy succinic acid. Tartaric acid is used as a chemical intermediate and a sequestrant,as well as in tanning, effervescent beverages, baking powder, ceramics, photography, textile processing,mirror silvering,and metal coloring. Chemical Properties Tartaric acid is odorless, but has a characteristic acid taste. Naturally occurring tartaric acid is generally of the L-configuration (based on the absolute configuration of D-glyceric acid). The L-forms of tartrates are dextrorotatory in solution and thus are designated as L(+)-tartrates. For a detailed description on this chemical, refer to Burdock (1997). Occurrence d-Tartaric acid occurs in many fruits or other parts of the plant, free or combined with potassium, calcium or magnesium. It is also reported found in raw, lean fish, white wine, red wine and port wine. Uses DL-Tartaric acid is used as a synergist for antioxidants, emulsifier, sequestrant and flavoring agent. It is also added with citric acid to prepare effervescent salts, thereby enhancing the taste of oral medications. It is also utilized in pigments, processing aids, ink, toner and colorant products. It acts as a chelating agent in metal and farming industries. Further, it is used as lubricant and grease. It is mixed with sodium bicarbonate and used as a leavening agent in food preparation. In the pharmaceutical industry, it is utilized in the preparation of tartar emetic, which is used in cough syrup as an expectorant. Uses DL-Tartaric acid can be used: In the Debus–Radziszewski reaction as a weak acid for the synthesis of imidazolium ionic liquid. As an additive in electrochemical deposition technique for the synthesis of bismuth thin films to be used as X-ray absorbers. As a complexing agent for the synthesis of nano-crystalline indium tin oxide (ITO) powder. As a dopant for the synthesis of polyaniline nanofibers and nanotubes by oxidation polymerization. Preparation The tartrates used in commerce are obtained as a by-product of wine manufacture and have the L(+) configuration. Produced from argols or wine lees, which are formed in the manufacture of wine by extracting the potassium acid tartrate, transforming this into the calcium salt and then acidifying with dilute sulfuric acid; also by oxidation of d-glucose with nitric acid. The dl-tartaric acid is obtained by boiling the d-tartaric acid with an aqueous solution of NaOH or by oxidation of fumaric acid. The l- and the meso-tartaric acid are also known, but are less important.   DL-Tartaric acid Preparation Products And Raw materials Raw materials Hydrogen peroxide-->Maleic anhydride-->Maleic acid-->D(-)-Tartaric acid-->Tungstic acid-->Sodium pyruvate-->(+/-)-TRANS-EPOXYSUCCINIC ACID-->CALCIUM TARTRATE-->CIS-EPOXYSUCCINIC ACID-->TRANS-2,4-PENTADIENOIC ACID-->DIHYDROXYFUMARIC ACID-->MESOTARTARIC ACID-->Sorbic acid Preparation Products Pyruvic acid-->Potassium sodium tartrate-->Potassium Bitartrate-->4-Hydroxy-D-(-)-2-phenylglycine-->Ammonium L-tartrate-->L(+)-Diethyl L-tartrate-->Potassium tartrate-->L-Antimony potassium tartrate-->(2S,3S)(-)-Dihydroxybutane-1,4-dioic acid diethyl ester-->Disodium tartrate dihydrate-->Kitasamycin tartrate Tag:DL-Tartaric acid(133-37-9) Related Product Information
