N-取代酰胺萃取分离铌、钽的性能良好.本文报导N,N-二仲辛基乙酰胺(DOAA)及N-仲辛基乙酰胺(MOAA)在HF-H2SO4中萃取铌、钽的机理.采用双对数法、连续变量法、饱和法及饱和有机相分析法研究了络合物的组成,并根据负荷有机相的红外光谱讨论了被萃络合物的结构.

N-Substituted amides possess excellent properties for the separation of niobium and tantalum.This paper describes a study on the mechanism of the extraction of niobium and tantalum by a solution of N, N-di-sec-octylaoetamide (DOAA) or N-mono-sec-octylacetamide (MOAA) in xylene from the HF-H2SO4 system.
