AMINE SEPARATION METHOD

WIPO Patent Application WO/2024/043296

A1

An amine separation method comprises a separation step for separating an amine through chromatography using: a stationary phase obtained by supporting, on a carrier, a ligand having a crown ether-like cyclic structure; and a mobile phase that contains a salt of a cation and an acid anion in a concentration of 0.2-50.0 mM and contains a solvent having a water content of at most 50 vol%.
