Tartaric acid

Tartaric acid is a white crystalline dicarboxylic acid Tartaric acid was first isolated from potassium tartrate known to the ancients as Louis Pasteur continued this research in 1847 by investigating the shapes of tartaric acid crystals which he found to be asymmetric Pasteur was the first to produce a pure sample of levotartaric acid

The corresponding hydroxide orthoantimonious acid Sb(OH) 31 can be obtained in a somewhat impure form by precipitating tartar emetic with dilute sulphuric acid or bet::er by decomposing antimonyl tartaric acid with sulphuric acid and drying the precipitated white powder at too C Antimony tetroxide is formed by strongly heating either the trioxide or pentoxide

Optical Isomers of Tartaric acid (HOOC-CHOH-CHOH-COOH) Two chiral carbon atoms are present in tartaric acid The difference in spatial arrangements of various groups in tartaric acid results in d-tartaric acid l-tartaric acid and an active form known as meso form In addition to these racemic modification another inactive form also exist Dextro tartaric acid rotates the plane of polarization

Tartaric acid can be produced by natural and synthetic routes The natural route involves the recovery of the reddish precipitated salt potassium bitartarate from argol the sediment in wine vats The synthetic chemical route involves the production of the racemic mixture of tartaric acid from maleic anhydride

Dictionary entry overview: What does racemic acid mean? • RACEMIC ACID (noun) The noun RACEMIC ACID has 1 sense: 1 the optically inactive form of tartaric acid that is often found in grape juice Familiarity information: RACEMIC ACID used as a noun is very rare

Differences between Racemic Mixture and Meso

A racemic mixture is a combination of organic compounds known as enantiomers It is optically dormant due to the presence of equal amounts of non-super imposable mirror images A meso compound is a molecule having more than one identical stereocenters and an identical or superimposable mirror image

Examples of chiral derivatizing agents (a k a chiral resolving agents) are tartaric acid and brucine The method was introduced (again) by Louis Pasteur in 1853 by resolving racemic tartaric acid with optically active (+)-cinchotoxine One modern-day method of chiral resolution is used in the organic synthesis of the drug duloxetine: In one of its steps the racemic alcohol 1 is dissolved in a

Racemic acid is an old name for an optically inactive or racemic form of tartaric acid It is an equal mixture of two mirror-image isomers (enantiomers) optically active in opposing directions The naturally occurring form of the acid is the right-handed Tartaric acid's sodium-ammonium salt is unusual among racemic mixtures in that during crystallization it can separate out into two kinds of
