چکیده

A new bio-friendly catalyst was synthesized via impregnation of coconut chaff. Maghemite-coconut chaff (MCC) showed an excellent capability for catalyzing the Mannich reaction in the water as a clean solvent. MCC was easily separated from the reaction medium with a magnet due to its ideal magnetic activities. Moreover, the catalyst showed an outstanding recyclability potential. While the catalyst structure and its properties were investigated by XRD, SEM, and VSM, organic products were fully identified by IR, CNMR, and HNMR.
