    Description / Table of Contents: Basic Aluminium Salts and their Solutions. XIX. Nature of Aluminium Cations in Highly Basic Highly Concentrated Aluminium Chloride SolutionsIt is shown that in highly concentrated basic aluminium chloride solutions (cAl ≈ 7.7 mol · l-1; r = OH/Al = 2.48), prepared by dissolving aluminium metal in substoichiometric quantities of hydrochloric acid, polymeric aluminium cations (Alpoly) dominate. By dilution of these solutions also increasing amounts of monomeric cations (Almono) occur. On aging Almono reacts with Alpoly forming small portions of tridecameric Al13O40 cations (Al13).On the basis of these results literature data, after which corresponding commercial basic aluminium chloride solutions contain essentially Al13 cations, are critically discussed.
    Notes: Es wird gezeigt, daß in hochkonzentrierten basischen Aluminiumchloridlösungen (cAl ≈ 7,7 mol · l-1; r = OH/Al = 2,48), hergestellt durch Umsetzen von metallischem Al mit einem Unterschuß an Salzsäure, überwiegend polymere Aluminiumkationen (Alpoly) vorliegen. Bei Verdünnung der Lösungen treten daneben zunehmend monomere Kationen (Almono) auf, die im Verlaufe der Alterung mit dem Alpoly unter Bildung geringer Anteile von tridekameren Al13O40-Kationen (Al13) reagieren.Ausgehend von diesen Befunden werden Literaturangaben, wonach in kommerziellen basischen Aluminiumchloridlösungen entsprechender Konzentration und Basizität im wesentlichen Al13-Kationen auftreten sollen, einer kritischen Wertung unterzogen.
