METHOD FOR PRODUCING ETHYLENE AMINES AND ETHANOL AMINES BY THE HYDROGENATING AMINATION OF MONOETHYLENE GLYCOL AND AMMONIA IN THE PRESENCE OF A CATALYST

摘要

The invention relates to a method for producing ethylene amines and ethanol amines by the hydrogenating amination of monoethylene glycol and ammonia in the presence of a catalyst. Said method is characterised in that it uses a catalyst with an active mass containing ruthenium and cobalt, but no additional metal from group VIII and no metal from group IB, in the form of catalyst moulded bodies. If said bodies are spherical or in the form of bars, their respective diameters are 3 mm, if in tablet form their height is 3 mm and all other shapes have an equivalent diameter L = 1/a' of 0.70 mm, where a' represents the external surface area per unit volume (mms2/mmp3). The bodies are represented by the formula (I), where Ap represents the external surface area of the catalyst moulded body (mms2) and Vp represents the volume of said catalyst moulded body (mmp3).
