Neutral uranium dimer complexes and selective extraction properties of a new paratertiary butyl 1,3-acid-diethyl amide substituted calixarene ligand
- The solvent extraction of uranium(VI) with a paratertiary butyl 1,3-acid-diethyl amide substituted calixarene ligand in dichloromethane has been studied. UO2+2was found to extract into the dichloromethane phase with a metal:ligand ratio of 1. X-ray crystallographic analysis of a single crystal indicated a dimeric species of 2 UO2+2:2 ligands. The extraction mechanism is pH dependent due to the increased availability of deprotonated hydroxyl groups with increase in pH.
