| 摘 要： | 以乙醇胺（MEA）为原料,ZSM-5分子筛为催化剂,采用缩合工艺合成了乙撑胺。考察了反应温度、n（NH3）∶n（MEA）及空速LHSV（MEA）对乙醇胺的影响。反应所用原料为质量分数50%的乙醇胺溶液。为增加乙二胺（DEA）和哌嗪（PIP）的选择性,适宜的条件为：n（NH3）∶n（MEA）=13,LHSV（MEA）=0.300 h-1,反应温度350℃,选择性S（DEA）=17.78%,S（PIP）=20.46%,S（TE-DA）=21.99%,转化率约为70%。

| Abstract: | The ethyleneimine was synthesized by condensation reaction with the ZSM-5 molecular sieve as a catalyst,2-aminoethanol(50% aqueous solution) and ammonia as the raw materials.The influence of reaction temperature,the amount of ammonia,and LHSV of 2-aminoethanol on the 2-aminoethanol were investigated.To increase the selectivity of ethylenediamine and piperazine,the optimum technological condition was found that: the conversion was 70% and the selectivity of EDA,PIP,TEDA in products were 17.78%,20.46%,21.99% ... |
