A family of novel ionic liquid with L-alanine and choline chloride as environmentally benign materials have been synthesized and grafted on Fe3O4 nanoparticles using easy preparation techniques. The structure of ionic liquid supported on Fe3O4 nanoparticles (IL-Fe3O4 NPs) characterized by various analyses such as FE-SEM, EDX, XRD, NMR, FTIR and VSM. The catalytic activities of this catalyst are examined in the Mannich reaction for synthesis of beta-aminocarbonyl compounds under ultrasonic irradiation. The recyclability of catalyst is investigated, and the results have indicated that the catalyst can be recycled six times without obvious activity decreasing. (C) 2016 Elsevier B.V.
