Method for separation of enantiomeric isomers by simulated moving bed chromatography

摘要

The present invention provides a method having a high productivity for preparative separation by simulated moving bed chromatography. That is, in a filler for enantiomeric isomer separation by simulated moving bed chromatography, which has a porous carrier carrying a polysaccharide derivative thereon and has a TS coefficient in a range of 0.55 to 1.20, the TS coefficient being defined by the below-shown formula (I), and obtained by using an enantiomeric isomer separation column for simulated moving bed chromatography in which the filler is filled in a column tube by a slurry filling method: TS coefficient=[Vc-[t(TS)-t(blank)]xFR]/[t(TS)-t(blank)]xFR, (I) wherein Vc (cm³): a column volume; FR (ml/min.): a flow velocity; t(TS) (min.): an elution time for tetrakis(trimethylsilyl)silane (=TS); and t(blank) (min.): an elution time for TS in the state where the column is not connected.
