title: Application of zone-melting technique to metal chelate systems-X Zone-refining of bis(acetylacetonato)beryllium(II), tris(acetylacetonato)aluminium(III) and bis(di-isovalerylmethanato)copper(II).
abstract: Bis(acetylacetonato)beryllium(II), tris(acetylacetonato)aluminium(III) and bis(di-isovaleryl-methanato)copper(II) were zone-refined. Also crude beryllium(II), aluminium(III) and copper(II) salts were purified by zone-melting the above-mentioned chelates, obtained by precipitation from aqueous methanol solutions. Some contaminants were excluded at the stage of chelate formation and the remainder were concentrated at the terminal end of a zone-refining column.
