羟基与酯基官能团化离子液体的合成

Synthesis of Ionic Liquid Functionalized with Hydroxyl and Ester

以溴代或氯代醇或酯和吡啶为原料合成了三个离子液体前体即溴化N-羟乙基吡啶、氯化N-羟己基吡啶和N-甲氧羰乙基吡啶氯代盐;分别将它们与四氟硼酸钠进行复分解反应得到相应的离子液体即N-羟乙基吡啶四氟硼酸盐、N-羟己基吡啶四氟硼酸盐和N-甲氧羰乙基吡啶四氟硼酸盐。利用核磁共振波谱对三个离子液体进行了表征。

Three precursors which were N-hydroxyethyl pyridium bromide, N-hydroxyhexyl pyridium chloride, and N-methoxylcarbonylmethyl pyridium chloride for preparation of the correspondent tetrafluoroborate ionic liquid compounds were synthesized by the reaction of pyridine with bromo or chloro alcohol and ester. Three tetrafluoroborate ionic liquid compounds were prepared by means of metatheses of the precursors with sodium tetrafluoroborate and their structures were characterized by 1H NMR.
