在对次锕系元素(MA)进行嬗变前,需将中子吸收截面较大的镧系元素与MA分离。目前,R-BTBP类萃取剂在分离三价锕系与镧系元素方面具有潜在的应用价值。本文合成了乙基取代的BTBP(C2-BTBP)。以6,6′-二氰-2,2′-联吡啶为原料,经两步反应,合成了6,6′-二(5,6-二乙基-1,2,4-三嗪-3-基)-2,2′-联吡啶。合成路线如图1所示。
Before the minor actinide (MA) transmutation, it is necessary to separate the lanthanides with large neutron absorption cross sections from the MA. At present, R-BTBP extractants have potential application in the separation of trivalent actinides and lanthanides. In this paper, ethyl-substituted BTBP (C2-BTBP) was synthesized. Using 6,6’-dicyano-2,2’-bipyridyl as raw material, 6,6’-bis (5,6-diethyl-1,2,4-triazine- 3-yl) -2,2’-bipyridine. Synthetic route shown in Figure 1.
