Answer:

A process for separating the para and ortho isomers of a halogen substituted toluene from a feed mixture of the same. Separation of the isomers is effected by selective adsorption and desorption and is susceptible to various flow schemes for performing continuous adsorptive separations. The process uses an X type zeolite adsorbent having calcium, barium, potassium, or combinations thereof as cations and a mixed desorbent containing chlorobenzene and/or bromobenzene and alicyclic

Abstract:

A process for separating the ortho-isomer of chlorotoluene from a feed mixture containing ortho- and para-chlorotoluene by selective adsorption and desorption with an L zeolite adsorbent having potassium or potassium and sodium cations at cation exchange sites and a desorbent containing chlorobenzene or mixtures thereof with a saturated aliphatic hydrocarbon and especially 10-50% chlorobenzene and 50-90% saturated aliphatic hydrocarbon. The ortho-chlorotoluene is relatively non-absorbed on the adsorbent and is recovered prior to more strongly adsorbed species in a rejective separation process.
