Abstract

PURPOSE: To absorb and separate p-isomer form a mixture containing toluidine isomers or N-substituted toluidine isomers, selectively, easily, with simple operation, by the use of a solid adsorbent containing titanium oxide.
CONSTITUTION: A mixture containig toluidine isomers or N-substituted toluidine isomers (pref. having 1W3C alkyl as substitutent group) is made to contact with a solid adsorbent containing titanium oxide (pref. anatase-type titanium dioxide) pref. at room temp. to 120°C. The para isomer can be easily and selectively adsorbed and separated by this simple operation.
