Using three kinds of novel β-diketone of different alkyl-chain length (1-phenyl-1, 3-octanedione, 1-phenyl-1, 3-tetradecanedione and 1-phenyl-1, 3-icosanedione) and four kinds of neutral phosphorus compounds of different alkyl-chain length (tri-n-butylphosphine oxide, tri-n-octylphosphine oxide), tri -n-butyl phosp ate and tris (2-ethylhexyl) phosphate, the extraction equilibrium of lithium was investigated, and the synergistic effect of these extraction systems was examined, in order to determine the optimum extraction system for lithium.<BR>It is found that lithium is synergistically extracted by the mixture of β-diketone and neutral phosphorus compounds, and that the ability of lithium extraction with the synergistic reagent of trialkylphosphine oxide is higher than that with tri-alkylphosphate. However, the effect of alkyl-chain length of β-diketone on the extraction equilibrium constants is negligibly small. These results are confirmed by molecular modeling of the extractants and synergistic reagents.
