Abstract Under the guidance of the principle of independence and self-reliance, thesubstituted amide-type A-101 extractant has been successfully synthesized. Thistype extractant showed easy synthesis, better physico-chemical properties andhigher selectivity. Dialkylacetamide is one of weakly basic extractant with car-bonyl as functional group. Examples are given in which A-101 type extractanthas been used to extract and separate rare metals from ore concentrates, e.g.niobium-tantalum separation, thallium extraction, molybdenum-rhenium separa-tion, gallium extraction etc., in every case satisfactory results on industrial scalehave been obtained.
