摘要： The novel lipophilic metal extractants of the class dialkyldiaza-tetraalkyloctanediamide (DADA) useful to selectively separate trivalent americium (sup. 241 Am) from trivalent lanthanides are represented by the formula 1: Wherein R is a C1 to C5 normal alkyl and R′ is a C4 to C8 normal and branched alkyl group. The compounds are synthesized at high yield and purity by the reaction of corresponding N,N′-dialkylethylenediamine and N,N-dialkyl-2-chloroacetamide. The separation is achieved by utilizing the soft-soft interaction between the trivalent actinides and ‘N’ atoms of the extractant. Both soft donor “n” and hard donor ‘O’ sites are incorporated in the molecule for better extraction of trivalent actinides over trivalent lanthanides. Thus, this molecule can be used as selective extractant to separate trivalent actinides from trivalent lanthanides.
摘要翻译：用于从三价镧系元素中选择性分离三价ium（sup。241 Am）的二烷基二氮杂 - 四烷基辛二胺类（DADA）的新型亲脂性金属萃取剂由式1表示：其中R是C1至C5正烷基，R'是 C4〜C8正支链烷基。通过相应的N，N'-二烷基乙二胺和N，N-二烷基-2-氯乙酰胺的反应，以高产率和纯度合成了这些化合物。通过利用三价锕系元素和萃取剂的“N”原子之间的软 - 软相互作用来实现分离。软质供体“n”和硬供体“O”位点都被并入分子中，以便在三价镧系元素上更好地提取三价锕系元素。因此，该分子可用作选择性萃取剂以从三价镧系元素分离三价锕系元素。
