ABSTRACT:
A process for preparing triethylenediamine by passing an ethanolamine, ethyleneamine, piperaziHe 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 caustic solution.
