摘 要:异恶唑开环、烷基化得到产物为(Z)-3-乙氧基丙烯腈、(E)-3-乙氧基丙烯腈和3,3-二乙氧基丙腈的混合物。经柱层析分离提纯各组分,并采用气相色谱法、核磁共振氢谱法和气相色谱/质谱法,对其进行了组分分析和结构表征。其中(Z)-3-乙氧基丙烯腈、(E)-3-乙氧基丙烯腈的分离、核磁氢谱结构表征未见报道。

Abstract:The mixture of 3-ethoxyacrylonitrile and 3,3-diethoxypropionitrile was gotten as product from isoxazole by ring opening,separated with column chromatography and checked quantitatively by GC. The 1H NMR and MS were used in study of their relative structures. The separation method of E/Z-isomers of 3-ethoxyacrylonitrile was studied and their structures were characterized by 1H NMR data first.
Key words:(Z)-3-Ethoxyacrylonitrile;(E)-3-Ethoxyacrylonitrile;3,3-diethoxypropionitrile;GC;1H NMR;GC/MS
