How racemic mixture of lactic acid resolved?

Answer 1

A racemic mixture of lactic acid, which contains equal amounts of both enantiomers (D- and L-lactic acid), can be resolved using methods like selective crystallization, where one enantiomer is preferentially crystallized out of the mixture. Another common method involves enzymatic resolution, where specific enzymes selectively react with one enantiomer, allowing the other to remain unreacted. Additionally, chiral chromatography can be employed to separate the enantiomers based on their interaction with a chiral stationary phase. These techniques help isolate the desired enantiomer for further use.
