关于三胺混合物的气相色谱分析,国内外已有一些报导。宫原昭二郎以三乙醇胺为固定相;Iosoire等以二乙醇胺和十二烷醇为混合固定相;周桂兰等。则在自己的工作中以十六烷醇代替十二烷醇。鉴于这些工作,我们结合本厂实际情况,对一、二、三甲胺的分离分析进行了试验研究,并拟定出一、二、三甲胺水溶液的气相色谱分 Gas chromatographic analysis of triamine mixtures has been reported at home and abroad. Miharahara Zajiro to triethanolamine as stationary phase; Iosoire such as diethanolamine and dodecanol as stationary phase; Zhou Guilan and so on. In their own work with cetanol instead of dodecanol. In view of these work, we combined with the actual situation of our factory, carried out the experimental study on the separation and analysis of one, two and three methylamine, and developed the gas chromatographic fraction of the aqueous solution of one, two and three methylamine
