| Abstract: | A condensed molybdate complex was extracted from acidic solutionsof pH 0·5−5 by propylene carbonate (PrCO3). The extracted complex exhibited a yellow color and had three characteristic absorption maxima at 225 mμ, 260 mμ, and 325 mμ. The extraction data indicated that the extract was highly condensed and adducted three propylene carbonate molecules. Propylene carbonate behaves not only as an extracting reagent but also as the reagent which reacts with molybdate in adequate acidic solution to produce the extractable species. |
