Abstract

The electrochemical dissolution of metallic lanthanum in ethanol (EtOH) is studied in the presence of 0.5 M lithium chloride with acetylacetone (HAA), dibenzoylmethane (HDBM), tenoyltrifluoroacetone (HTTA), and benzoylacetone (HBA). Adducts of lanthanum tris-β-diketonates, specifically, La(AA)3 · 0.5EtOH, · La(DBM)3· 2EtOH, La(TTA)3 · 1.5EtOH, and La(BA)3 · EtOH are extracted from solution. Electrooxidation of lanthanum during electrolysis is accompanied by its chemical dissolution. The composition of the obtained compounds is confirmed by IR spectroscopy, thermogravimetry, isothermic heating, and elemental analysis for the metal.
