Synthetic method of N-ethyl ethylenediamine

[0029] The present invention will be described in detail below in combination with specific embodiments.

[0030] The whole reaction was carried out in a closed autoclave. 150 g of ethylamine aqueous solution (the content of ethylamine was calculated as 105 g), 100.3 g of cycloethylamine and 5 g of molybdenum oxide were added into the autoclave together, the temperature was raised to 50 ° C, and the reaction was stirred for 5 h. After the reaction is completed, molecular sieves are added to the reaction liquid to seal and dry the liquid. The next day, the molecular sieves were filtered off, and the filtrate was distilled under reduced pressure by a water pump. The fraction at 38-41°C was collected and weighed to obtain 196g, with a purity of 99% and a yield of 95.6%.
