Synthesis of Functional Ionic Liquids by Thermal Heating and Ultrasonic-Assisted Methods
1-(2-Methacryloyloxy)ethyl-3-butylimidazolium bromide, a kind of functional ionic liquid containing ester group, was synthesized by two synthesis methods, denoted as thermal heating method and ultrasonic-assisted method. The optimal synthesis condition of the thermal heating method is discussed. Comparison of the two methods shows that ultrasound significantly enhances the efficiency of the reaction. The ultrasonic-assisted method is quite promising in synthesis of ionic liquids with mild condition and high efficiency.
