ABSTRACT OF THE DISCLOSURE An electrolyte for electrolytic capacitor containing within an aprotic solvent an alkyl quarternary ammonium salt of aliphatic saturated monocarboxylic acid as as solute. An electrolyte for electrolytic capacitor according to the invention may conveniently be prepared by adding one equivalent amount of aliphatic saturated monocarboxylic acid to a methylene chloride solution of alkyl ammonium hydrogen- sulfate for reaction with subsequent addition of two equiva- lent amounts of alkali hydroxide. A deposit is removed from the reaction product with subsequent vacuum drying to obtain an anhydrous salt and then dissolving said anhydrous salt to an aprotic solvent until a desired conductivity is obtained, for example, as an approximately 10% by weight solution.
