Abstract
Separation of close boiling point mixtures of alkylphenols, such as p-cresol/2,6-xylenol, and m-cresol/ 2,6-xylenol has been attempted using NaX zeolites. Effect of the cation on the selectivity has also been investigated. The NaX zeolite adsorbs p-cresol and m-cresol selectively from their mixtures with 2,6-xylenol, while CaX and BaX zeolites preferentially adsorb 2,6-xylenol. The selectivity seems to be decided by the diffusion in the zeolite framework.
