Separation studies were conducted to sep. palladium (Pd) or platinum (Pt) from acidic solutions using 15 hydrophobic ionic liquids (ILs) capable of forming a binary phase with acidic aqueous solution This study considered two cases. The first was to find high-efficient ILs capable of separating metals from a single solution, and the second was to find ILs capable of selectively separating Pt from an acidic mixture solution of Pd and Pt. In addition, we also considered toxic effect of ILs for greener separation process. For this studies, we exptl. examined the separation efficiencies of the ILs, and discuss the properties with their toxicities, theor. predicted by previously presented toxicity prediction model, were compared. The results revealed that the extraction efficiency of ILs for Pd and Pt from acidic solutions depends on the types of IL and metal concentration In the separation study on Pd in a single metal solution, trihexyltetradecylphosphonium bromide [P6,6,6,14]Br and trioctylmethylammonium chloride [N8,8,8,1]Cl efficiently separates Pd from acidic solutions, while the separation on Pt in its single metal solution, 1-benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [IM1-1Bz][(CF3SO2)2N], 1-methyl-3-dodecylimidazolim bis(trifluoromethylsulfonyl)imide [IM12][(CF3SO2)2N], 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [IM16][(CF3SO2)2N], [P6,6,6,14]Br and [N8,8,8,1]Cl led to high efficiencies. Moreover, in the study to selectively sep. Pt from a mixed solution of Pd and Pt, [IM1-1Bz][(CF3SO2)2N] and [IM16][(CF3SO2)2N] have significant separation efficiency. When comparing the efficiencies and toxicities of the two ILs, [IM1-1Bz][(CF3SO2)2N] is more efficient, but it is more toxic than [IM16][(CF3SO2)2N]. Thus, for sustainable development, [IM16][(CF3SO2)2N] can be considered as a better option. Moreover, in order to understand the partitioning mechanisms of ILs we developed quant. structure-activity relationship models with R2 values greater than 0.91. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Related Products of 5137-55-3).
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. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Related Products of 5137-55-3
