“…Such as solvent-free reaction, or reaction with water as the medium and using room temperature ionic liquid as the reaction solvent (Welton, 1999). Ionic liquid has the advantages of low vapor pressure, non-flammable, good thermal stability, recyclable, compared with other organic solvents (Sowmiah et al, 2009;Çınar et al, 2016;Bystrzanowska et al, 2019). On the other hand, assisted by microwave radiation, the rate of organic reaction is also greatly improved, and simple operation, high yield, simple post-treatment characteristics (Santagada et al, 2009;Sharma et al, 2012).…”
