Abstract: The invention relates to a method for producing triethylenediamine by converting piperazine on a zeolite catalyst, which in addition to SiO2 contains an oxide of at least one additional bivalent, trivalent or tetravalent metal M. Said catalyst is characterised in that the zeolite has a molar ratio Si/M of > 100. The invention uses in particular a zeolite of the type ZSM-5. By using the zeolite, the adverse formation of the by-product 2-ethylpiperazine can be suppressed, whilst obtaining high piperazine conversion rates and low amounts of excess water, thus significantly simplifying preparation.

Abstract: Preparation of triethylenediamine (I, 1,4-diazabicyclo(2,2,2)octane) by reacting ethylenediamine (II) at 250-500 deg C in presence of a zeolite catalyst (A) containing at least one metal (M) in oxidation states II, III or IV, as the oxide. Preparation of triethylenediamine (I, 1,4-diazabicyclo(2,2,2)octane) by reacting ethylenediamine (II) at 250-500 deg C in presence of a zeolite catalyst (A) containing at least one metal (M) in oxidation states II, III or IV, as the oxide. When M is aluminum, the SiO2:M oxide mole ratio is over 1400:1, when M has an oxidation state II or III the mole ratio is over 100:1, and when M has an oxidation state IV, the mole ratio is over 10:1.
