Extraction of zinc(II) and copper(II) from HCl solutions with solutions of mono- and dialkynyl-substituted quaternary ammonium halides in chloroform and toluene is more efficient than the extraction with saturated quaternary ammonium salts and occurs by different mechanism. The dependences of the metal distribution factors on the HCl concentration have two maxima whose positions (absolute and relative) and relative intensities depend on the particular extractant, metal, and diluent.
使用单炔基取代的季铵卤化物的氯仿和甲苯溶液从 HCl 溶液中萃取锌 (II) 和铜 (II) 比使用饱和季铵盐萃取更有效,并且通过不同的机理进行。金属分布因子对 HCl 浓度的依赖性有两个最大值,其位置(绝对和相对)和相对强度取决于特定的萃取剂、金属和稀释剂。
