DEFINITION

Classification: 562/401

Racemization or separation of optical isomers:

(under subclass 400) Processes directed to the racemization or separation of optical isomers and includes the separation of diastereomers as well as the resolution of racemic mixtures of enantiomers.

(1) Note. This subclass contains patents wherein the separation is carried out by a chemical reaction, such as with a resolving agent, followed by physical separation and regeneration of the desired isomeric component.
