| Abstract: | 1 -Butyl -3-methylimidazolitun bromide Bmim ] Br as intermediate of ionic liquid was synthesized using N- methylimidazole and 1-butylbromide as raw materials. The effects of reaction conditions such as reaction time, reaction temperature, molar ratio of N - methyl imidazole to 1 -butylbromide, and solvents on the product yield were examined. The product was characterized using 1H NMR and FT - IR. The result showed that the yield was 91.93 % under the reaction conditions as follows ： reaction temperature 60 ℃, reaction time 24 hours, molar ratio of N- methylimidazole to 1-butylbromide 1 ： 1.2. |
