도데칸에 녹인 아세틸아세톤과 트리부틸인산으로 묽은 질산우라닐수용액에서 우라늄(Ⅵ)을 추출했다. pH 1 이상에서 이 혼합추출제의 상승적 효과가 관측되었다. 추출되는 화학종은 1:2:1 및 1:2:2 우라닐-아세틸 아세톤-트리부틸 인산착물이다. 이들 반응의 추출정수들을 측정하였다.

Uranium (Ⅵ) was extracted from dilute aqueous solutions of uranyl nitrate with acetylacetone and tri-n-butyl phosphate in n-dodecane. Synergistic effect was observed with the mixed reagents above pH 1. The species extracted are the 1:2:1 and the 1:2:2 uranyl-AA-TBP complexes. The extraction constants for these reactions have been determined.
