C12P41/007 - CPC Classification

Classification description:

Processes using enzymes or microorganisms to separate optical isomers from a racemic mixture by reactions involving C-N bonds, e.g. nitriles, amides, hydantoins, carbamates, lactames, transamination reactions, or keto group formation from racemic mixtures by reactions involving acyl derivatives of racemic amines
