متن کاملNonanomalous Electrodeposition of Zinc-Iron Alloys in an Acidic Zinc Chloride-1-ethyl-3-methylimidazolium Chloride Ionic Liquid
The electrodeposition of iron and Zn-Fe alloys on polycrystalline nickel was investigated in the 40.0-60.0 mol % zinc chloride1-ethyl-3-methylimidazolium chloride ionic liquid containing iron~II! at 90°C. Iron~II! was electrochemically reduced to iron metal before the reduction of zinc~II! to zinc metal, and anomalous codeposition of Zn-Fe did not occur in this ionic liquid. Underpotential depo...
متن کاملGreen extraction of Niobium and Tantalum from Kenticha Tantalite ore using 1-Ethyl-3-Methyl Imidazolium Chloride ionic liquid
The decomposition of the Ethiopian Kenticha tantalite ore was studied using the KOH fusion and H2O leaching system at 400 0C for a 1 h reaction time. The experimental results obtained showed that 27 wt% of Ta2O5 was mainly transformed into insoluble KTaO3, not to be KNbO3, and as well, into the dissolved liquor containing 94.73 vol% of Nb2O5 and 75.80 vol% of Ta2O5. The observations, supported ...
متن کاملSelective oxidation of cyclohexanol to cyclohexanone in the ionic liquid 1-octyl-3-methylimidazolium chloride.
Ionic liquid (IL) 1-octyl-3-methylimidazolium chloride was found to effectively intensify cyclohexanol oxidation and resulted in 100% conversion of cyclohexanol with 100% selectivity to cyclohexanone using hydrogen peroxide as an oxidant and WO(3) as a catalyst. The effect of the IL as a solvent is discussed with the support of COSMO-RS theory.
