以吡咯烷为二级胺，合成了Ｎ－辛酰吡咯烷（ＯＰＯＤ）、 Ｎ－癸酰吡咯烷（ＤＰＯＤ）、 Ｎ－月桂酰吡咯烷（ＤＯＰＯＤ）等三种新型双取代酰胺类－Ｎ－酰化吡咯烷类（Ｎ－ａｃｙｌｐｙｒｒｏｌｉｄｉｎｅ ＡＰＯＤ）萃取剂，利用红外光谱、核磁共振谱对其结构进行了表征，并对该类萃取剂萃取铀的性能进行了研究。
Three novel bis-substituted amides-N-octanoyl pyrrolidine (OPOD), N-decyl pyrrolidine (DPOD) and N-lauroyl pyrrolidine (DOPOD) The structure of N-acylpyrrolidine APOD was characterized by FTIR and NMR, and the properties of uranium extracted by this kind of extractant were studied.
