The Uses of 1-Butyl-3-methylimidazolium bromide

It is an ionic liquid used in a Heck reaction. It is also used in assessing the factors responsible for ionic liquid toxicity to aquatic organisms via quantitative structure-property relationship modeling

Preparation

Preparation of 1-butyl-3-methylimidazolium bromide: A three-necked 50 mL round bottom flask was charged with N-methylimidazole (0.10 mol) followed by dropwise addition of 1-bromobutane (0.11 mol) at 70 ℃. After the addition was completed, the resulting mixture was stirred at 140 ℃ for 1.5 h. The combined organic layer was washed three times by ethyl acetate and vacuum-dried overnight at 70 ℃.
