Noncyclic polyethers exhibiting lithium ion selectivity have been synthesized. Their competitive alkalimetal-ion transport through liquid membranes has been investigated, and the influence of their structures on the rates and selectivities of cation transport has been demonstrated. It has been found that the introduction of the oxytrimethylene chain on the polyethers is significant for the appearance
已经合成了表现出
锂离子选择性的非环状聚醚。已经研究了它们通过液膜的竞争性碱
金属离子传输,并证明了它们的结构对阳离子传输速率和选择性的影响。已经发现,在聚醚上引入氧三亚甲基链对于
锂离子高选择性的出现具有重要意义,而且端基的种类可能在决定阳离子传输速率或对
锂离子的选择性。与具有未取代的
喹啉基的聚醚相比,在聚醚的
喹啉端基的2-位引入甲基大大提高了对
锂离子的选择性。
