Abstract
1,225,509. Electrolytic capacitors. LES CONDENSATEURS SIC-SAFCO. 22 Oct., 1968 [27 Oct., 1967], No. 50092/68. Heading H1M. An electrolyte for an aluminium anode electrolytic capacitor comprises at least 0À1% by weight of a di- and/or tri-alkyl ammonium salt of a dicarboxylic acid, at least 1% of a dicarboxylic acid, 0À1 to 10% by weight of phosphoric acid dissolved in a solvent selected from dialkyl amides, N-methylpyrrolidone, γ-butyrolactone and γ-valerolactone, and contains 0À01 to 3% of water. The salt may be derived from the amines di- or tri-ethyl or butyl amines or N-methyl butylamine and the acid may be malonic, succinic, adipic, maleic or fumaric acid. The amide solvent may be dimethyl formamide or dimethyl acetamide. The electrolyte may contain boric acid.
