Synthesis and Application of Nanocrystalline-Cellulose-Supported Acid Ionic Liquid Catalyst in Pechmann Reaction
Nanocrystalline-cellulose-supported acidic ionic liquid carrying SO3H functional group was prepared using nanocrystalline cellulose, imidazole and 1,4-butane sultone as the source chemicals. The prepared nanocrystalline-cellulose-supported ionic liquid catalyst was characterized by AFM and SEM and its catalytic activity in the reaction of resorcinol with ethyl acetoacetate was tested in a solvent-free condition. The effects of reaction time, reaction temperature, and the ratio of catalyst on the conversion of resorcinol were investigated. A variety of coumarin derivatives were obtained in good yield in the absence of solvent.
