<p>At least one xylenol isomer can be separated and purified from a mixture, which contains the specific xylenol isomer and at least one organic substance other than the specific xylenol isomer, by bringing the mixture into contact with 1,1-di(4-hydroxyphenyl)-cyclohexane as a host compound to form a complex of the specific xylenol isomer as a guest compound with the host compound and then having the specific xylenol isomer released from the complex. The mixture may contain at least two xylenol isomers consisting of 2,4-xylenol and 2,5-xylenol, and at least one of the xylenol isomers can be separated and purified by having it released from its complex with the host compound.</p> |
