| titleOfInvention | A method for separating p-xylene |
| abstract | A method for separating p-xylene from a blend comprising p-xylene and, in addition, at least one other xylene isomer (including ethylbenzene) and optionally C.sub.9. aromatic hydrocarbons by contacting the mixed batch with an adsorbent containing a crystalline aluminosilicate which contains a Group IA or IIA metal ion of the Periodic Table under adsorption conditions at the exchangeable cation sites, with selective adsorption of p-xylene at said and the raffinate stream containing less strongly adsorbed other xylene isomers is then contacted with the desorbent containing diethyl toluene under desorption conditions to remove the p-xylene-containing adsorbent to remove the p-xylene from the desorbent as an extract stream. In particular, the metal of the group Ia or IIA is potassium and / or barium |
