    Description / Table of Contents: Summary A study has been made of the suitability of several tertiary aromatic amines for the extraction of zinc from acid and neutral solutions. These amines may be placed in three groups: those with good, those with poor extraction capabilities, and those which simulate a good extraction but in truth act as labelling agents. The majority should be placed in the second category. The third group includes above all the following amines: 3-(Benzylmethylamino)-propanol, N-methyl-N-propargyl-benzylamine and N-benzyl-N,N-dimethylethylenediamine. 3-(Dimethylamino)-methylindole in weakly acid medium and N, N-dimethylhomotryptamine in the neutral region can be looked upon as good extraction agents for zinc. Nickel is entirely or partially masked by most amines.
    Notes: Zusammenfassung Die Eignung einiger tertiärer aromatischer Amine zur Extraktion von Zink aus sauren und neutralen Lösungen wurde untersucht. Man kann diese Amine in drei Gruppen einteilen: solche mit gutem, solche mit schlechtem Extraktionsvermögen und solche, die zwar eine gute Extraktion vortäuschen, die aber tatsächlich als Maskierungsmittel wirken. Die Mehrzahl ist in die zweite Gruppe einzuordnen. In die dritte Gruppe gehören vor allem die Amine 3-(Benzylmethylamino)-propanol, N-Methyl-N-Propargyl-Benzylamin und N-Benzyl-N,N-Dimethyläthylendiamin. 3-(Dimethylamino)-Methylindol in schwach saurem Medium und N,N-Dimethylhomotryptamin im Neutralbereich können als gute Extraktionsmittel für Zink angesehen werden. Nickel wird von den meisten Aminen ganz oder teilweise maskiert.
