Abstract
Resolution of a racemic mixture of organic materials by simulated moving bed chromatography using a chiral stationary phase can be routinely effected at atypically low values of k' with recoveries of at least 95% and an optical purity of at least 95%. In particular, values in the range 0.1<k'<1.0 are recommended with a resulting savings in mobile phase consumption, inventory, and recovery.
