Hi,

 

guys,

 

I know tartaric acid include DL-tartaric acid, L (+)- Tartaric Acid, Anticaking L (+)-Tartaric Acid and D (-)- Tartaric Acid.

 

Do you know the difference between them?

 

Thank you for your help.

they know dextro, levo and meso forms, plus mixes

 

and... is that the proper sense?

Ammonium sodium tartrate is one of the few compounds that separate into dextro and levo forms when crystallizing. I suppose tartaric acid is then used to separate L and R forms of synthesized amines. The tratrate is one cadidate for my suggested Czochralski separation:
