Liquid-liquid extraction of copper(II) with cyclic and acyclic tetrathioethers

The liquid-liquid extraction of copper(II) with cyclic and acyclic tetrathioethers (L) into 1,2-dichloroethane was examined. When hexanitrodiphenylamine ion (A −) was used as the counter anion, the extracted species [Cu(II)L(OH)] + A − was predominant at pH > 6.0. The logarithmic extraction const...

Zusammenfassung:The liquid-liquid extraction of copper(II) with cyclic and acyclic tetrathioethers (L) into 1,2-dichloroethane was examined. When hexanitrodiphenylamine ion (A −) was used as the counter anion, the extracted species [Cu(II)L(OH)] + A − was predominant at pH > 6.0. The logarithmic extraction constants log k ex were 14.65 and 14.88 for the cyclic tetrathiatetradecane and the corresponding acyclic tetrathiapentadecane, respectively.
