摘要
考察了瓜环在不同酸度、IA金属离子中的溶解性变化情况,并利用其溶解性的变化来合成分离瓜环。结果表明,在一定条件下,选择适当酸度或添加适当金属离子作为模板有利于瓜环的定向合成及分离。
Influence of acidity and IA metal ion on Solubility of Cucurbit [n = 5 -8] urils have been examined. And die experimental results show that the application of acidity and IA metal ion on Solubility of Cucurbit [ n = 5 - 8 ] urils to Synthesis And Separate of Cucurbit [ n = 5 - 8 ] urils usually increases efficiency and decreases cost.
