以氯乙酸乙酯和氮杂环化合物(1-甲基咪唑、吡啶、N-乙基哌啶、N-甲基吗啉)为原料, 采用两步法合成了一类新型的酯类离子液体, 对合成的12个化合物进行了元素分析, 1H NMR谱和一些物理性质的测定. 大多数化合物的熔点低于100 ℃, 为室温离子液体. 所合成离子液体的热稳定范围都比较宽, 性质稳定.

关键词: 离子液体, 酯类, 功能离子液体, 合成

A series of ionic liquids containing ethyl acetate moiety on the cations were designed and synthesized, using starting material ethyl chloroacetate and N-heterocyclic compounds (1-methylimidazole, pyridine, N-ethylpiperidine and N-methyl morpholine) through two synthesis steps. All 12 synthesized compounds were characterized by some physical property measurement, elemental analysis and 1H NMR spectra. The melting points of the most compounds are below 100 ℃. They are room temperature ionic liquids. The relative stability of the prepared ionic liquids owes to the wide scope of their thermostability.

Key words: synthesis, functionalized ionic liquid, ester, ionic liquid
