Abstract
A feed containing a mixture of at least two alkylphenol isomers is contacted with a zeolite adsorbent to allow an alkylphenol isomer in the mixture to be selectively adsorbed on the adsorbent, and then the adsorbent is contacted with an aliphatic ketone desorbent to desorb the adsorbed isomer.
