Thermal and Kinetic Analysis

In the synergistic extractions of metal ions with the systems 1,1,1-trifluoro-3-2′-thenoyl acetone (HTTA) and neutral organophosphorus compounds, stable complexes have been isolated from the organic phase. These have the following formulae: UO2(TTA)2S1, UO2(TTA)2S3, Th(TTA)4S1 and Rare Earth (TTA)3S2, where S = a neutral organophosphorus compound. The infra-red spectra of these complexes have been obtained and are discussed in terms of various possible structures.
