Claims
- 1. A process for separating 3,5-xylenol from an isomer mixture containing 3,5-xylenol, which comprises contacting the isomer mixture with an adsorbent of a zeolite of the Y type containing at least one of an Ag cation and a Cu cation, whereby 3,5-xylenol is separated and recovered as a raffinate component, and expelling the isomers adsorbed in the adsorbent by a desorbent to regenerate the adsorbent, said desorbent being selected from the group consisting of alcohols having 3 to 6 carbon atoms and ketones having 4 to 6 carbon atoms.
- 2. A process according to claim 1, wherein the Y type zeolite adsorbent contains at least one of the Ag cation and the Cu cation in an amount of 5 to 100 mole% of all the cations.
- 3. A process for separating 3,5-xylenol from an isomer mixture containing 3,5-xylenol, which comprises contacting the isomer mixture with an adsorbent of a zeolite of the Y type containing at least one of an Ag cation and a Cu cation, whereby 3,5-xylenol is separated and recovered as a raffinate component.
