ABSTRACT:
A racemate may be resolved into its enantiomers by stereoselective adsorption on a crystalline molecular sieve having an assymetric crystal structure for example zeolite ZSM11. The resolution may be assisted by the presence of an enantiomer of a compound separable from that of the racemate either preadsorbed on the molecular sieve or included in a polar solvent solution of the racemate to be treated. Resolution of an alkyl aryl sulphoxide racemate is exemplified.
