Popis:	The extraction of calcium, magnesium and lithium with 1-phenyl-3-methyl-4-stearoylpyrazol-5-one and with 1-phenyl-3-methyl-4-lauroylpyrazol-5-one was studied and separation factors were determined. A good separation of alkaline earth metal ions from lithium chloride can be achieved. 1-Phenyl-3-methyl-4-benzoylpyrazol-5-one in the presence of trioctylphosphine oxide is also suitable as an extractant for lithium whereas other alkali metals are extracted to only a minor extent. The distribution constant of this ligand was obtained for the investigated system. From the extraction data, stability constants of the formed complexes were determined.
