Hydrophobic deep eutectic solvents (DESs) are considered to be clean and green alternatives to traditional organic solvents for metal ion extraction Herein, a series of novel hydrophobic DESs were synthesized via the combination of methyltrioctylammonium chloride ([N8881]Cl) as hydrogen bond acceptors (HBAs) and saturated fatty acids or saturated fatty alcs. as hydrogen bond donors (HBDs). Then, the DESs were used for palladium(II) recovery from acid solution The factors that affect palladium(II) extraction (including the DES species, contact time, DES dose, solution pH, and temperature) were extensively investigated. The DESs exhibit excellent performance for extracting palladium(II) from hydrochloric acid media, and more than 99% of palladium(II) was extracted under optimal conditions. UV-vis, 1H NMR, and FTIR spectral characterizations confirm that the extraction mechanism of palladium(II) involves an anion exchange reaction whereby PdCl2-4 anions in the aqueous phase replace Cl- anions in DES to form ion-pairs with [N+8881] via electrostatic interactions. Meanwhile, N8881:1-hexanol (1:1) and N8881:hexanoic acid (1:2) exhibit excellent selectivity for palladium(II) over other impurity metal ions. Also, palladium(II) in the loaded DES phase was efficiently recovered as elemental palladium via the hydrazine hydrate reduction method; thus, the DES could be reused for at least 5 cycles. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3COA of Formula: C25H54ClN).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.COA of Formula: C25H54ClN
