| 摘 要： | 采用气相色谱法测定乙醇胺还原氨化制乙二胺反应液中乙醇胺、乙二胺、哌嗪及二乙烯三胺的含量。选择手性色谱柱,程序升温及乙二醇内标物作为色谱条件,在此条件下各种物质能很好地分离,该方法的检出限(3S/N)为0.05～0.38mg·L~(-1),在3个浓度水平上加入标准溶液作回收试验,测得回收率为86.4%～115.5%,相对标准偏差(n=5)为0.55%～0.83%。

| Abstract: | Five compounds,i.e.,ethanolamine.ethylenediamine,aminoethylpiperazine,piperazine and diethylenetriamine,in the reaction solution of preparation of ethylene diamine by reductive amination of ethanolamine,were determined by gas chromatography,with chiral capillary column.Gradient elevation of column temperature and using of ethylene glycol as internal standard were adopted in the analysis.Clear separation of the compound was attained under the optimized conditioa Detection limits(3S/N)of the method were found... |
