PROCESS FOR THE ISOMERIZATION OF O-, M- AND/OR P- TOLUIDINE

摘要

Abstract of the disclosure:The invention relates to a process for the iso-merization of o-, m- or p-toluidine, or of a mixture ofthem, on a zirconium containing zeolite catalyst of thepentasil type. Catalysts of this type are distinguishedby particularly high activity and a long useful life.The invention particularly relates to the preparation ofm-toluidine by isomerization of o- and/or p-toluidine onzirconium-containing zeolite catalysts of the pentasiltype.
