摘　　要：合成了对叔丁基杯［４］芳烃及其衍生物乙酰基甲氧基对叔丁基杯［４］芳烃（简称Ｌ）。研究了萃取剂Ｌ对各种金属离子的萃取，发现该试剂对Ｎａ￣＋有特殊的萃取效率，测定了Ｌ萃取Ｎａ￣＋的萃取平衡常数，并讨论了其萃取机理。p-tert- butylcalix[4] arene and its derivative tetramethoxy p-tert- butylcalix[4] arenetetraketone(L)have been synthesized.The extraction of metal ions,including alkali metdl ions,akaline earth metal ions,and several transition metal ions such as Cu￣(2+),Zn￣(2+),Ni￣(2+), Cd￣(2+)andHg￣(2+), is studied.It is found that the extractant L has the special extraction efficiency for Na￣+.The extraction mechanism is also discussed in this paper,and the extraction equation can be writ-ten as:Na￣++Pi￣-+L=NaItPi_(o),where NaLPi represents the composition of the complex,The-extraction equilibrium constant for Na￣+ has been determined to be lg K_(ex)=6. 59 at 30±1℃.
