二氨基乙腈及三胺的合成及表征

The synthesis and characterization of Bi(2-nitrilethyl)aminoacetonitrile and tris(2-nitrilethyl)amine

利用加成反应合成了两种新化合物二 ( 2 -腈基乙基 )氨基乙腈及三 ( 2 -腈基乙基 )胺 ,用红外光谱、1 H -NMR核磁共振谱、元素分析、ES -MS质谱及热重分析对其结构和热性质进行了表征。结果证实所制备的两种化合物即为目标化合物 ,这两种化合物热性质相似 ,在 30 0℃以下具有较好的热稳定性。

Two new compounds bi(2-nitrilethyl)aminoacetonitrile and tris(2-nitrilethyl)amine was synthesized by the additive reaction. It was characterized by IR spectra, 1 H-NMR, elemental analysis, ES-MS and TG-DTA . The results indicated that the two compounds synthesized were practically the objective compounds. The two compounds have similar thermal behaviors, and have high thermal stability under 300℃.
