摘要
Mn3+/Mn2+间接电合成对甲氧基苯甲醛的反应中,为了防止残留有机物污染电极,降低电流效率,用离子液体[BMIM]PF6对化学反应液进行萃取,与有机溶剂苯萃取效果进行比较,并讨论酸度、温度对其萃取效果的影响,结果表明:用离子液体[BMIM]PF6萃取效果优于苯,pH值为1、温度为30℃时,萃取效果好。
In the indirect electrosynthesis of anisaldehyde by Mn^3＋/Mn^2＋ reaction, in order to prevent organic resi- dues from polluting electrode and thus reducing the current efficiency, ionic liquid--[BMIM]PF6 is used to leach liquid of chemical reaction. We research the extraction abilities of the [BMIM]PF6 compared with benzene and discuss the effects of the acidity and temperature on the extraction abilities. The results show that ionic liquid--[BMIM]PF6 has better ex- traction abilities than benzene, and when pH = 1, a temperature of 30℃ a better effect in extraction can be obtained.
