以N-甲基吗啉和N-乙基吗啉为原料合成了系列新型的氮二烷基吗啉季铵盐类离子液体, 所有新化合物经元素分析、1H NMR确认了其结构, 同时测定了该类化合物的热稳定性、电导率以及对聚丙烯腈的溶解能力. 试验结果表明, 大多数化合物的熔点较低, 为室温离子液体. 该类化合物具有较好的热稳定性, 可应用于电极和表面活性剂领域. 且N-甲基-N-丁基吗啉盐酸盐具备对聚丙烯腈的溶解能力.

关键词: 离子液体, 吗啉季铵盐, 热分析, 聚丙烯腈

Seven quaternary N-morpholinium chlorides were synthesized by treating N-alkylmorpholine with chlorohydrocarbon. 1H NMR, 13C NMR spectroscopy and elemental analysis were used to characterize the synthesized products. Thermal properties of the new compounds were studied using TG/DTA. Some of the synthesized compounds seem to be suitable for ionic liquid applications because melting points were observed for most of them. And the good thermal stability of these compounds enables their potential use for example as phase-transfer catalysts and electrolytes. The results show N-methyl-N-butylmorpholinium chloride has dissolving capacity to the polyacrylonitrile.

Key words: ionic liquid, N-dialkylmorpholinium salt, thermal analysis, polyacrylonitrile
