Tartaric acid

Naturally occurring tartaric acid is chiral meaning that it has molecules that are non-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 D-(+)-tartaric acid or dextrotartaric acid

Stereoisomerism

Diastereomers are stereoisomers not related through a reflection operation They are not mirror images of each other These include meso compounds cis–trans isomers E-Z isomers and non-enantiomeric optical isomers Diastereomers seldom have the same physical properties In the example shown below the meso form of tartaric acid forms a diastereomeric pair with both levo and dextro tartaric

Comparison of supercapacitive behaviors of polyaniline

Compared with citric acid‐doped PANI D‐tartaric acid‐doped PANI shows higher specific capacitance (525 F/g at 1 A/g) and cyclic stability The good electrochemical behaviors of D‐tartaric acid‐doped PANI might be attributed to the two carboxyl groups of D‐tartaric acid which are beneficial to the oriented growth of PANI chains
