ABSTRACT:
A process for preparing triethylenediamine and piperazine 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 treated with a passivating agent which is a silicon-containing compound capable of deactivating the acidic sites on the zeolite surface.
