PROCESS FOR PRODUCING ETHYLENEAMINES

摘要

Process for producing ethyleneamines by reacting monoethanolamine (MEOA) with ammonia in the presence of a transition metal heterogeneous catalyst in which the catalytically active mass of the catalyst before the treatment with hydrogen contains oxygen-containing compounds of aluminium, copper, nickel and cobalt and the shaped catalyst body in the case of bead shape or rod shape in each case has a diameter of < 3 mm, in the case of tablet shape has a height of < 3 mm and in the case of all other geometries in each case has an equivalent diameter L = 1/a' of < 0.70 mm, where a' is the external surface area per volume unit (mm_s ²/
