Abstract: The production technology of monoethanol amine and its downstream products including ethylene diamine，diethylene triamine，ethylene imine，etc. is reviewed. The characteristics of reductive amination catalysts and condensation amination catalysts in ethylene diamine synthesis are presented，and the effects of supports and promoters of the catalysts on the catalytic performance are also discussed. It is pointed out that the future development should be mainly concentrated on more efficient and also more selective catalysts and environmentally friendly processes.
