摘要
An adsorptive separation process for separating ortho-chloronitrobenzene from a feed mixture comprising ortho-chloronitrobenzene and at least one other isomer of chloronitrobenzene, which process comprises contacting the feed mixture with an adsorbent comprising a type X or type Y zeolite containing at the exchangeable cationic sites one or more cations selected from the group consisting of Groups IA, IIA and the transition metals of the Periodic Table of Elements, selectively adsorbing substantially all of the said ortho-chloronitrobenzene to the substantial exclusion of the remaining isomers and thereafter recovering high-purity ortho-chloronitrobenzene. A desorption step may be used to desorb the adsorbed ortho-chloronitrobenzene.
