Pyrazolone derivatives in the extraction of hydragyrum ions (II) from chloride solutions

The assessment of the extraction ability of di-anti-pyril- and di-pyrazolinyl-methanes, evidence from the hydragyrum ions extraction from chloride solutions into chloroform, was appraised. The influence of reagents basicity, chain length of alkyl radical at the central atom of the molecule reagent on distribution ratio of hydragyrum ions was established. The composition, the mechanism of the extracted complexes were determined, the extraction constants and the distribution ratios of the hydragyrum (II) chloride complexes were calculated. (author)
