Mao, Jiajun published the artcileSynergistic extraction of uranium(VI) with 1-phenyl-3-methyl-4-acylpyrazolone-5 and neutral extractants, Computed Properties of 1691-93-6, the main research area is uranium extraction phenylmethylacetylpyrazolone neutral extractant; dioctylsulfoxide pyrazolone extraction uranium; TOPO pyrazolone extraction uranium; TBP pyrazolone extraction uranium.
The synergistic extraction of uranium(VI) from hydrochloric acid solution with five chelating agents: 1-phenyl-3-methyl-4-benzoylpyrazolone-5 (PMBP), 1-phenyl-3-methyl-4-acetylpyrazolone-5 (PMAP), 1-phenyl-3-methyl-4-(2′-chlorobenzoyl)pyrazolone-5 (PMCBP), 1-phenyl-3-methyl-4-(p-nitrobenzoyl)pyrazolone-5 (PMNBP) and 1-phenyl-3-methyl-4-trifluoroacetylpyrazolone-5 (PMTFP) plus the neutral extractants TBP, dioctyl sulfoxide (DOSO) and TOPO in chloroform were investigated. The extraction coefficients were greater for such mixtures than the individual component. The formulas of the extracted species were determined to be UO2A2B (where HA = chelating agent, B = neutral extractant). Extraction power of these chelating agents increases as follows: PMCBP > PMNBP > PMTFP = PMBP > PMAP. Synergistic extraction power of the neutral extractants increases as follows: TOPO > DOSO > TBP. The extraction equilibrium constants were calculated The mechanism of the synergistic extraction and possible structure of the extracted species are discussed.
Journal of Radioanalytical and Nuclear Chemistry published new progress about uranium extraction phenylmethylacetylpyrazolone neutral extractant; dioctylsulfoxide pyrazolone extraction uranium; TOPO pyrazolone extraction uranium; TBP pyrazolone extraction uranium. 1691-93-6 belongs to class pyrazoles-derivatives, name is 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one, and the molecular formula is C12H9F3N2O2, Computed Properties of 1691-93-6.
