“…PC is less volatile, non-toxic, and a highly polar solvent and is used in cosmetics such as a nail polish remover and as an LSI washer in semiconductor manufacture. Although some studies on the application of PC in metal extraction have been reported [9][10][11] , PC has not become popular as an extracting solvent yet. Other than the favorable properties as an extraction solvent mentioned above, PC has an UCST of 72ºC.…”

This study was undertaken to investigate the extraction of In 3+ and Ga 3+ by 7-(4-ethyl-1-methyloctyl)-8-hydroxy-quinoline (Kelex100), which has been found to be a slow extraction process. Homogeneous liquid-liquid extraction utilizing upper critical solution temperature of 4-methyl-1,3-dioxolan-2-one (propylene carbonate, abbreviated as PC) was used to eliminate the interface and speed up the extraction, since distribution between two phases was thought to be the rate-determining step. The effect of contact time on the percentage of metal extraction was examined at 80ºC using Kelex100 dissolved in toluene and PC solutions and the difference between two solvents was evaluated. The results clearly show that the use of homogeneous liquid-liquid extraction using PC with Kelex100 is faster than traditional two phase extraction.

“…Generally, since the extracting solvent affects to extractability in the ion association extraction systems more strongly than that in chelate extraction system, PC was mainly examined in the former systems. For example, B. G. Stephens Vol.29 No.3 (2018) et al has reported the extraction of ferroin complexes using PC as a solvent with different derivatives of 1,10-phenanthroline [3][4][5] , and PC was also used for the extracting solvent in the polarographic determination of halo-complex ions of some metals 6,7) . On the other hand, only few attempts to applying PC to chelate extraction system were reported 8,9) , and the paper on the solvent extraction of metal ions using BC could not be found at all by reviewing the literature.…”

4-Methyl-1,3-dioxolan-2-one and 4-ethyl-1,3-dioxolan-2-one are well-known solvent in the name of propylene carbonate (PC) and butylene carbonate (BC), respectively, and PC is classified to level 1 in terms of combustibility and health hazard by National Fire-Protection Association. Therefore, PC is less toxic and environment-friendly solvent compared to the usual solvents, such as hexane and toluene. PC and BC are not only safe but also are having strong polarity, however, their application to solvent extraction of metal chelates as an extraction solvent were not carried out so much. Then, in this study, PC and BC were applied to N,N-dioctyldiglycolamic acid (DODGAA) extraction of lanthanides as the diluent and their extractabilities were compared with that of hexane. Lanthanum and scandium were found to be affected with solvent comparatively strongly to the other lanthanides. It was observed in the slope analysis of in the relationship between log D vs. pH plots that the some slopes of straight lines in DODGAA-PC and DODGAA-BC system deviated from theoretical value of 3. The possibilities of the change of metal ion concentration based on the volume change due to the mutual dissolution and the formation of different kind of complex other than LnR 3 were considered as the causes for the deviations in a slope analysis and were examined experimentally.

Abstract4-Methyl-1,3-dioxolan-2-one is well known solvent in the name of propylene carbonate (PC) and has good solvent properties, e.g. low toxicity, less flammable, high density and less viscous, nevertheless the application of PC in solvent extraction has only been considered in a few cases. Then, availability of PC to solvent extraction was examined by applying it to the extraction of three different kinds of analyte, hydrophilic neutral species, a chelate and an ion association complex. At first, 6 water miscible solvents, i.e., methanol, isopropanol, tert-butanol, acetone, acetonitrile and tetrahydrofuran were arbitrarily selected as hydrophilic neutral species and the extractability of PC and cyclohexane for these solvents were examined. Dioctyldiglycolamic acid (Abbreviate as DODGAA) complex of lanthanide (Ln 3+ ) was chosen as an example of chelate extraction and was extracted with PC and n-hexane, respectively. Ion association extraction was investigated with the extractability of bis(1,10-phenanthroline) iron(II) complex (Fe(phen) 3 2+ 2X -) by using PC, toluene and nitrobenzene. In all cases, PC showed the significant extractability compared to common solvents.
