补充资料:离子缔合物萃取
分子式:
CAS号:

性质:由金属配位离子与异电性离子以静电引力的作用结合成不带电的化合物,称为离子缔合物,此缔合物具有疏水性而能被有机溶剂萃取。可以分为三类:(1)形成羊盐的缔合物。能发生这类萃取的萃取剂是含氧的有机溶剂,如醚类、醇类、酮类和酯类等,常用的有乙醚、环己醇、甲基异丁基甲酮(MIBK)、乙酸乙酯等;(2)形成铵盐的缔合物,如次甲基蓝在酸性条件下与BF4-缔合成铵盐缔合物。发生这类萃取要用含氮的有机萃取剂,如大分子胺和碱性染料等;(3)形成其他缔合物。如砷盐(R4As+)、鳞盐(R4P+)与ReO4-形成缔合物[(C6H5)4As+ReO4-]而被氯仿萃取。离子缔合物萃取的特点是容量大,有利于基体元素的分离。
