SEPARATION METHOD OF FAT-SOLUBLE MATERIAL BY PSEUDO-MOVING BED CHROMATOGRAPHY USING NORMAL PHASE COLUMN, AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a highly-efficient unsaturated aliphatic acid purification method and a device therefor, by solving problems in an existing unsaturated aliphatic acid purification method.SOLUTION: In a separation method, SMB chromatography is used, which includes columns filled with at least two kinds of gels selected from a group comprising silica gel, silver nitrate-impregnated gel and polymer gel, preferably, at least three silver nitrate-impregnated gel columns and at least one silica gel column. A device therefore is also provided.
