Abstract

Method for preparing piperazine of formula I by reacting diethanolamine (DEOA) of formula II with ammonia in the presence of hydrogen and a metal containing supported catalyst. Before the catalyst is reduced with hydrogen the catalytically active mass of the catalyst contains oxygen containing aluminum copper nickel and cobalt compounds and 0.2 to 5.0 wt.% oxygen containing tin compounds calculated as SnO and the reaction is carried out in the liquid phase at an absolute pressure ranging from 160 to 220 bar at a temperature ranging from 180 to 220°C ammonia is used at a molar ratio ranging from 5 to 25 in relation to the DEOA used in the process the method being carried out in the presence of 0.2 to 9.0 wt.% hydrogen relative to the total amount of DEOA and ammonia used in the process.
