摘要：
Herein, a new nanocomposite was prepared by immobilizing ionic liquid on magnetic lignin as a support with a core-shell structure (Fe3O4-Lignin-SO3/IL). The properties of the prepared catalyst were studied using various analyses such as FE-SEM, FT-IR, TEM, VSM, EDS, XRD, and TGA techniques. The resultant nanocomposite exhibits remarkable catalytic activity for synthesizing biscoumarin derivatives. The magnetic nanocatalyst can be readily and quickly separated from the reaction mixture and can be reused for at least five successive reaction cycles without a significant reduction in efficiency.
