Process for the separation of di-substituted benzene |
| abstract |
An adsorptive separation process for separating the para-isomers of a di-substituted benzene from a feed mixture comprising the para-isomer and at least one other isomer. One substituted group is NO2- and the other group is a normal hydrocarbon having less than 6 carbon atoms per molecule, the halogens, NH2-, NO2- or C 3BOND N-. The process comprises contacting the feed mixture with an adsorbent comprising crystalline silica having a silica/alumina mole ratio of at least 12, selectively adsorbing substantially all of the para-isomer to the substantial exclusion of the remaining isomers and thereafter recovering high-purity para-isomer by means of desorption with an appropriate desorbent material. |
