Abstract
A process for separating and recovering para-ethylphenol from methyl-ethylphenol and other alkyl phenols is described using an X zeolite adsorbent having ion exchangeable sites exchanged with barium ions, potassium ions or a mixture of barium and potassium ions. Selective adsorption of para-ethylphenol occurs possibly for recovery of the para-ethylphenol.
