用丙烯睛和己二胺可合成环氧树脂固化剂。借助核磁共振(NMR)、红外光谱(IR)、质谱(MS)分析该固化剂组成。结果表明：当己二胺(HMD)、丙烯睛(AN)按摩尔比为1:1反应时，除主要产物氰乙基己二胺外，产物中同时存在二氰乙基己二胺。
用丙烯睛和己二胺可閤成環氧樹脂固化劑。藉助覈磁共振(NMR)、紅外光譜(IR)、質譜(MS)分析該固化劑組成。結果錶明：噹己二胺(HMD)、丙烯睛(AN)按摩爾比為1:1反應時，除主要產物氰乙基己二胺外，產物中同時存在二氰乙基己二胺。

The curing agent for epoxy is synthesized by reacting hexamethylenediamine with acrylonitrile.Synthesis method has been improved.The compositions of the curing agent are analyzed with infrared spectroscopy,mass spectroscopy and nuclear magnetic resonance.It is found that when.the reaction between hexamethylenediamine and acrylonitrile is carried out in the mole ratio of 1: 1,main product of the mono-cyanoethylation hexamethylenediamine and by-product of the bicyanoethylation hexamethylenediamine is produced at same time.
