Abstract
A composition comprising a chiral organic amine covalently linked via a carbamate, mercaptocarbamate, or urea linkage to a chain of atoms whose other terminus is covalently bound to a core support may be used as a solid phase chromatographic medium in the separation of racemic mixtures. An example is alpha-methylbenzyl amine bound through a carbamate linkage to a 3-propylsilyl group covalently bonded to an alumina support.
