摘 要:異惡唑開(kāi)環(huán)、烷基化得到產(chǎn)物為(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。經(jīng)柱層析分離提純各組分,并采用氣相色譜法、核磁共振氫譜法和氣相色譜/質(zhì)譜法,對其進(jìn)行了組分分析和結構表征。其中(Z)-3-乙氧基丙烯腈、(E)-3-乙氧基丙烯腈的分離、核磁氫譜結構表征未見(jiàn)報道。 |
關(guān)鍵詞:(Z)-3-乙氧基丙烯腈;(E)-3-乙氧基丙烯腈;3,3-二乙氧基丙腈;氣相色譜;核磁氫譜法;氣相色譜/質(zhì)譜法 |

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 |
