“…In nearly one hundred years of hydrometallurgy history, the importance of chemical factors in achieving the targeted performance of extraction has been widely recognized. Alkyl salicylaldoxime series (AS), the N-O type chelating organic agents, is widely used as extractants to extract copper, nickel, zirconium, and molybdenum (Moradi Ali, 2012;Jain et al, 2016). Jiang et al have investigated the performance of DZ988N (a mixture of equal volumes of 5-nonylsalicylaldoxime and 2-hydroxy-5-nonyl-acetophenone oxime) in separating copper from sulfate solution containing Cu 2+ , Fe 3+ , and Zn 2+ (Jiang et al, 2018).…”

The alkyl salicylaldoxime has attracted more and more attention recently due to the complex branched alkyl groups. In this study, a novel alkyl salicylaldoxime, tert-octylsalicylaldoxime, was successfully synthesized by the one-pot method. The yield and purity by the elemental analysis were 96.17 and 94.13%, respectively. The structure was confirmed by elemental analysis, FT-IR, 1H NMR (Nuclear Magnetic Resonance), 13C NMR spectroscopy, and MS. Results showed that tert-octylsalicylaldoxime with a new structure exhibited excellent extraction ability and selectivity for Cu(II) and can be successfully used to recover Cu from copper-nickel alloy electroplating wastewater. Thus, this product has the potential to be used as a powerful copper extractant in the future.

“…Alkyl salicylaldoximes (AS)-the N-O type chelating organic agents-are widely-used extractants which present excellent extraction efficiency for Cu(II) [6,7]. AS are comprised of a benzene ring, phenolic hydroxyl, ortho-directing oximido, and para-directing alkyl (i.e., R group).…”

Four kinds of alkyl salicylaldoxime (AS) were investigated to probe the effect of molecular structure on the extraction of Cu(II). With the augment of R groups, tert-octylsalicylaldoxime and nonylsalicylaldoxime have much stronger extraction ability for Cu(II) than salicylaldoxime and tert-butylsalicylaldoxime, which is consistent with the rise of hydrophobicity (Log P) of the extractants. The umbrella structure of the R group can endow tert-octylsalicylaldoxime with stronger steric-hindrance effect than nonylsalicylaldoxime, which results in the better separation efficiency of Cu(II) from Fe(III) for tert-octylsalicylaldoxime. The extraction ability of the extractants for Cu(II) is related to the hydrophobicity and molecular size, as predicted from quantum chemistry calculation.
