Application of Ionic Liquids in Hydrometallurgy
Ionic liquids, low temperature molten salts, have various advantages manifesting themselves as durable and environmentally friendly solvents. Their application is expanding into various fields including hydrometallurgy due to their unique properties such as non-volatility, inflammability, low toxicity, good ionic conductivity, and wide electrochemical potential window. This paper reviews previo...
متن کاملMagnetic ZnFe2O4 nanoparticles as an efficient catalyst for the oxidation of alcohols to carbonyl compounds in the presence of oxone as an oxidant
Zinc ferrite (ZnFe2O4) nanoparticles were synthesized via the auto-combustion assisted sol-gel method of Zn2+ and Fe3+ ions (molar ratio 1:2) in ammonia solution. The prepared nanomagnetic catalyst was characterized by IR, XRD, SEM and ICP. The diameter of the ZnFe2O4 MNPs (63.7 nm) was determined by Debye-Scherre equation via their XRD pattern. Nanomagnetic ZnFe2O4 efficiently catalyzes oxidat...

متن کاملMagnetic NiFe2O4 Nanoparticles as an Efficient Catalyst for the Oxidation of Alcohols to Carbonyl Compounds in the Presence of Oxone as an Oxidant
Nanomagnetic NiFe2O4 was used as the efficient, stable, reusable catalyst for selective oxidation of alcohols to their corresponding carbonyl compounds using oxone (potassium hydrogen monopersulfate) as oxidant in the presence of water as solvent at room temperature. The oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained wi...
متن کاملAn efficient ketone-catalyzed epoxidation using hydrogen peroxide as oxidant.
Epoxides are very important building blocks in organic synthesis.1 Dioxiranes, either isolated or generated in situ, have been shown to be extremely versatile epoxidation reagents.2-6 In nearly every case, the generation of dioxiranes uses potassium peroxomonosulfate (KHSO5) as oxidant (Scheme 1).7,8 During our recent study on asymmetric epoxidation using the fructose-derived ketone (1), we fou...
