Production of triethylenediamine using surface acidity deactivated zeolite catalysts

摘要

A process for preparing triethylenediamine by passing an ethanolamine, ethyleneamine, piperazine or morpholine over a pentasil-type zeolite at elevated temperature characterized by employing a ZSM-5 zeolite in the hydrogen or ammonium form which has been pretreated with an aqueous solution of a chelating agent capable of forming a chelate-aluminum complex.
