| Abstract: | A new ionic liquid (1-methyl-3-amylimidazolium acetate) was synthesized by solventing-out process and the sample was confirmed by 1HNMR.Anion exchange resin was used to synthesize .Because the difficult of purification of by recrystallization due to low freezing point in its synthesis process of intermediate (1-methyl-3-amylimidazolium bromine) the secondary deionized water as precipitation agent of recrystallization about purification of ionic liquid was used.The most precipitation agent addition ratio in ... |
