| Abstract: | The synthesis technology of N-ethylethylenediamine was developed,in which ethylenediamine and chloroethane were the raw materials,methanol was the solvent,and sodium methoxide was the acid binding agent.The ethylenediamine and methanol were reused and N-ethylethylenediamine was separated with the help of batch distillation.Then reaction conditions were optimized and the best conditions were as follows: the molar ratio of ethylenediamine and chloroethane was 1.5∶1,the reaction temperature was 40℃,and the reaction time was 4 h.The yield was 70.7%,and the product was characterized by gas chromatography and mass spectrometry. |
