    Abstract: Preparation of ethylene amine comprises reacting ethylene diamine in the presence of a transition metal heterogeneous catalyst. The catalytically active mass of the catalyst, before treatment with hydrogen, contains oxygen containing compound of aluminum, copper, nickel or cobalt, and that the catalyst molding is in a spherical or strand form with a diameter of less than 3 mm, in tablet form with a height of less than 3 mm, and in all other geometrical shapes with an equivalent diameter (L is I/a) of less than 0.70 mm (where a is A p/V p).
