Abstract
Abstract The application of an asymmetric resin containing optically active l -proline in the Cu 2+ form for the effective resolution of racemates by means of ligand-exchange chromatography is reported. It was found in the static sorption of proline enantiomers that the difference in its sorption energy reaches 450 cal/mole and depends on the degree of saturation of the resin by copper ions. Chromatographic data such as elution volumes and the concentration of ammonia in the eluent also depend on this factor.
