Abstract
A mixture of the enantiomorphic forms of crystalline optically active threonine or ammonium N-acetyl phenylolaminate, said compound being capable of forming a conglomerate, is resolved by passing an aqueous solution supersaturated with said mixture through a fixed bed comprising the crystals of one enantiomorph and allowing the same enantiomorph to crystallize on the fixed bed. The eluate may then be passed through a fixed bed comprising crystals of the other enantiomorph. A plurality of such pairs of beds may be used, each pair being in series or parallel; additional starting solution may be added during the circulation. Preferred operative temperatures are 15-40 DEG C.
