Process for separating mixed monochlorotoluene isomers, a plant for carrying out the process, and the isomers separated in this manner.

摘要

The invention relates to a process for separating mixed monochlorotoluene isomers, which comprises a first stage of adsorption carried out by passing said mixture through at least one column filled with a zeolite, and a second stage of deadsorption from said zeolite carried out by passing two deadsorbents in succession in the vapour phase through the column.
