PROCESS FOR THE SEPARATION OF CRESOL ISOMERS

摘要

An improved process for the separation of a paracresol from a feed mixture containing para-cresol and at least one other cresol isomer which process employs a crystalline aluminosilicate adsorbent to selectively adsorb para-cresol from the feed mixture. The improvement basically comprises employing a desorbent material comprising an alcohol to increase the selectivity of the adsorbent for para-cresol thereby allowing a more efficient separation with a higher purity extract stream recovered from the process.
