D(-)-Tartaric acid Chemical Properties,Uses,Production
Description
Tartaric acid is a white crystalline diprotic aldaric acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds, is commonly combined with baking soda to function as a leavening agent in recipes, and is one of the main acids found in wine. It is added to other foods to give a sour taste, and is used as an antioxidant. Salts of tartaric acid are known as tartrates. It is a dihydroxyl derivative of succinic acid.
Tartaric acid was first isolated from potassium tartrate, known to the ancients as tartar, circa 800 AD, by the alchemist Jabir ibn Hayyan The modern process was developed in 1769 by the Swedish chemist Carl Wilhelm Scheele.
Tartaric acid played an important role in the discovery of chemical chirality. This property of tartaric acid was first observed in 1832 by Jean Baptiste Biot, who observed its ability to rotate polarized light. Louis Pasteur continued this research in 1847 by investigating the shapes of ammonium sodium tartrate crystals, which he found to be chiral. By manually sorting the differently shaped crystals under magnification, Pasteur was the first to produce a pure sample of levotartaric acid.
Chemical Properties
Since the tartaric acid molecule contains two identical asymmetric carbon atoms, it has three rotary isomers, dextro-tartaric acid [L(+)-tartaric acid], levo-tartaric acid [D(-)-tartaric acid], and endo-racemic tartaric acid (Meso). Equal amounts of levotartaric acid were mixed with dextro-tartaric acid to obtain racemic tartaric acid or DL-tartaric acid. L-tartaric acid and dextro-tartaric acid are enantiomers. All naturally occurring tartaric acid is dextrorotatory. It is a colorless transparent crystal or a white fine to granular crystalline powder. The crystalline product contains 1 molecule of water of crystallization, odorless, stable in air, sour taste, acidity threshold value 0.0025%, acidity intensity of about 1.2 ~ 1.3 times that of citric acid, slightly astringent taste, burning with the odor of roasted sugar, with metal ion chelating effect. 1g dissolved in 0.8mL water (25℃), 0.5mL boiling water, 3mL ethanol. 0.3% aqueous solution of pH 2.4.
Uses
Pharmaceutic aid (buffering agent).
Definition
A crystalline naturallyoccurring carboxylic acid,(CHOH)2(COOH)2; r.d. 1.8; m.p.171–174°C. It can be obtained fromtartar (potassium hydrogen tartrate)deposits from wine vats, and is usedin baking powders and as a foodstuffsadditive. The compound isoptically active (see optical activity).The systematic name is 2,3-dihydroxybutanedioic acid.
Derivatives
Important derivatives of tartaric acid include its salts, cream of tartar (potassium bitartrate), Rochelle salt (potassium sodium tartrate, a mild laxative), and tartar emetic (antimony potassium tartrate). Diisopropyl tartrate is used as a catalyst in asymmetric synthesis.
Tartaric acid is a muscle toxin, which works by inhibiting the production of malic acid, and in high doses causes paralysis and death. The median lethal dose (LD50) is about 7.5 grams / kg for a human, ～5.3 grams/kg for rabbits and ～4.4 grams/kg for mice . Given this figure, it would take over 500 g to kill a person weighing 70 kg , and so it may be safely included in many foods, especially sour-tasting sweets. As a food additive, tartaric acid is used as an antioxidant with E number E334, tartrates are other additives serving as antioxidants or emulsifiers. .
Tartaric acid in wine
Tartaric acid may be most immediately recognizable to wine drinkers as the source of "wine diamonds", the small potassium bitartrate crystals that sometimes form spontaneously on the cork. These "tartrates" are harmless, despite sometimes being mistaken for broken glass, and are prevented in many wines through cold stabilization. The tartrates remaining on the inside of aging barrels were at one time a major industrial source of potassium bitartrate.
However, tartaric acid plays an important role chemically, lowering the pH of fermenting "must" to a level where many undesirable spoilage bacteria cannot live, and acting as a preservative after fermentation. In the mouth, tartaric acid provides some of the tartness in the wine, although citric and malic acids also play a role.
Stereo chemistry
Naturally occurring tartaric acid is chiral, meaning it has molecules that are not superimposable on their mirror images. It is a useful raw material in organic chemistry for the synthesis of other chiral molecules. The naturally occurring form of the acid is L-(+)- tartaric acid or dextrotartaric acid. The mirror-image (enantiomeric) form, levotartaric acid or D-()-tartaric acid, and the achiral form, mesotartaric acid, can be made artificially. The dextro and levo prefixes are not related to the D/L configuration (which is derived rather indirectly[8] from their structural relation to D- or L-glyceraldehyde), but to the orientation of the optical rotation, (+) = dextrorotatory, () = levorotatory. Sometimes, instead of capital letters, small italic d and l are used. They are abbreviations of dextroand levo- and, nowadays, should not be used. Levotartaric and dextrotartaric acid are enantiomers, mesotartaric acid is a diastereomer of both of them.
Tartaric acid is used to prevent copper(II) ions from reacting with the hydroxide ions present in the preparation of copper(I) oxide. Copper(I) oxide is a reddish-brown solid, and is produced by the reduction of a Cu(II) salt with an aldehyde, in an alkaline solution.
