Sm2O3 nanoparticles have been confirmed by FT-IR, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Energy-dispersive X-ray spectroscopy (EDX). The products were obtained in moderate to good yields under mild reaction conditions and identified by CHN analysis, NMR, and FT-IR spectra. The catalyst could be easily separated from the reaction mixture by centrifugation, washed, dried, and re-entered to a fresh reaction mixture 4 times without considerable loss of activity.}, keywords = {Morpholine,piperidine,Extract,Sm2O3 nanoparticles,Green Synthesis}, url = {https://jufgnsm.ut.ac.ir/article_87799.html}, eprint = {https://jufgnsm.ut.ac.ir/article_87799_775d9bbbe42103ff1c76e49dac5a1cf1.pdf} }
