Magnetic nanoparticles Fe3O4@SiO2@K10 as heterogeneous catalysts were found to be green and efficient for the synthesis of nitrile series by using aldehyde and hydroxylamine hydrochloride reflux under 80 0C conditions. The synthesized nanoparticles were analyzed using powder XRD, FT-IR spectra, EDX, WDX, and FE-SEM techniques. The size of the nanoparticles of the product was determined to be around 19 nm. That catalyst has the potential to function as a nano-reactor. The current approach has the following advantages: cleaner reaction, faster reaction, higher yield, easier set-up, and cheaper nanocatalyst availability. The nanocatalysts have been recycled and reused at least six times without losing their catalytic capabilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
