N-Ethylethylenediamine was synthetized innovatively by using diethyl carbonate which was a green industrial chemical and ethylenediamine as raw materials．The effects of many factors were investigated for the reaction of N-alkylation，which included different catalysts (β zeolites, mordenites and Y zeolites)，Y zeolites modified by alkaline metals (Li, Na, K) and reaction conditions．The results show that Y zeolites have the best catalytic activity；It is proved that NaY zeolites have the best catalytic effect；under the conditions of reacting temperature 240℃，n（ethylene diamine）/n（diethyl carbonate）＝2，Weight Hourly Space Velocity for 15.8/ h and flowing rate of nitrogen for 120 mL/min，the N - ethyl ethylenediamine yield can reach up to 93.1%．
