Efficient Synthesis of Benzo[b]pyrans and Knoevenagel Products Using Magnetically Separable Nano TPPA-IL-Fe3O4
A simple, efficient, and green practical approach to Knoevenagel condensation of malononitrile and different aldehydes has been developed using an ionic liquid functionalized on Fe3O4 magnetic nanoparticles as heterogeneous catalyst. This nanostructural catalyst has also been applied for the synthesis of 4H-benzo[b]pyran derivatives in water at room temperature in short reaction time. All of th...
متن کاملOne-pot synthesis of xanthones using a novel copper-based magnetically recoverable nanocatalyst
A versatile and straightforward strategy to construct a xanthone skeleton via an intermolecular catalytic coupling of 2-substituted benzaldehydes and a wide range of phenols has been developed. For this purpose, a novel and magnetically recoverable catalyst consisting of copper nanoparticles on nanosized silica coated maghemite in absence of ligand is presented. The reaction proceeds smoothly w...

متن کاملHydrogels Prepared from Cross-Linked Nanofibrillated Cellulose
Nanocomposite hydrogels were developed by cross-linking nanofibrillated cellulose with poly(methyl vinyl ether-co-maleic acid) and polyethylene glycol. The cross-linked hydrogels showed enhanced water absorption and gel content with the addition of nanocellulose. In addition, the thermal stability, mechanical strength, and modulus increased with an increase in the amount of nanocellulose in hyd...
متن کاملNanofibrillated Cellulose Surface Modification: A Review
Interest in nanofibrillated cellulose (NFC) has increased notably over recent decades. This bio-based nanomaterial has been used essentially in bionanocomposites or in paper thanks to its high mechanical reinforcement ability or barrier property respectively. Its nano-scale dimensions and its capacity to form a strong entangled nanoporous network have encouraged the emergence of new high-value ...
