摘要：

Silver(I) is very readily extracted from hydrochloric acid by solutions of tetrahexylammonium chloride (NR4C1) in I,2-dichloroethane as the ion-pair NR4+AgCl2-. Solutions of tri-n-hexylammonium chloride in nitrobenzene extract silver(I) as NR3H+AgCl32- but with solutions in m-xylene the species (NR3H+)2AgCl32- (or the quadrupole (NR3H+)(AgCl2-)(NR3H+)(Cl-)) is favoured. In each case the distribution ratio decreases with increase in chloride ion concentration. Hydrochloric acid itself is extracted more effectively by the quaternary liquid exchanger. © 1969.
