Abstract

PURPOSE: To adsorb and isolate a meta-isomer easily and selectively with a simple operation from a mixture containing toluidine isomers or N-substituted toluidine isomers, using a solid adsorbent containing Mg oxide.
CONSTITUTION: A mixture of toluidine isomers or N-substituted toluidine isomers (preferably the substitution group is a 1W3C alkyl) is treated with a solid adsorbent containing Mg oxide (preferably magnesia, silica-magnesia, alumina-magnesia, or silica-alumina-magnesia) preferably at room temp. to 120°C to adsorb and isolate a meta-isomer selectively. The meta-isomers can be isolated easily and selectively with a simple operation from a mixture containing toluidine isomers or N-substituted toluidine isomers.
