Synthesis and Screening of t-Bu-CyMe4-BTBP, and Comparison with CyMe4-BTBP
Artikel i vetenskaplig tidskrift, 2014
The effect of adding a t-butyl group to the core molecule of CyMe4-BTBP, with the aim of improving solubility in organic diluents, has been studied with regard to the extraction of Am(III) and Eu(III) from HNO3. Synthesis of t-Bu-CyMe4-BTBP is described in detail. Metal nitrates are extracted from nitric acid in the form of 1:2 complexes, M(NO3)(3)(BTBP)(2). Whether in 1-octanol, kerosene, or cyclohexanone diluents, t-Bu-CyMe4-BTBP extracts with larger distribution ratios but with slower kinetics than CyMe4-BTBP. The general trends previously observed for CyMe4-BTBP regarding the diluent and modifier influence were also found for t-Bu-CyMe4-BTBP.
