Reference of 342789-81-5,Some common heterocyclic compound, 342789-81-5, name is 1-Butyl-3-methylimidazolium methanesulfonate, molecular formula is C9H18N2O3S, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
5.2-1-butyl-3-methylimidazolium hexafluorophosphate (BMI.BF4)A mixture formed by 1,3-dimethyl imidazolium methanesulfonate (BMI.CH3SO3) (5.80 g; 24.6 mmol), sodium hexafluorophosphate (5.00 g; 29.8 mmol) and water (5.0 mL) was stirred at room temperature for 30 minutes. The resulting mixture, made up by two phases, was extracted with dichloromethane (3¡Á10 mL). The combined organic extract was washed with water (2¡Á20 mL) and dried with anhydrous sodium carbonate. The solvent was evaporated under vacuum and heated (80 C.), which produced the desired ionic liquid BMI.PF6 (6.64 g; 95% yield).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Butyl-3-methylimidazolium methanesulfonate, its application will become more common.
