Microwave-assisted rapid synthesis of ionic liquids

Rapid synthesis of ionic liquids were discussed in this study. Improve the traditional synthesis time and increase the yield of ionic liquids with microwave. The synthetic [Bmim]PF₆ ionic liquid were need in second step. Synthesized by microwave and conventional synthetic comparison the original 24 to 48 hours of reaction time reduced to 1 hour. [Bmim]PF₆ ionic liquids the best yield was about 49.5%. The results showed that the use of microwave assisted synthesis of ionic liquids can effectively reduce the synthesis time and the yield synthesis in comparison with the traditional reaction.
