ELECTROLYTIC SOLUTION FOR DRIVING ELECTROLYTIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic solution for driving an electrolytic capacitor, specifically a medium- and high-voltage aluminum electrolytic capacitor, excellent in high-temperature long-life characteristics and high in productivity of capacitors.SOLUTION: An electrolytic solution for driving an electrolytic capacitor contains a compound represented by the following formula (I), in an organic electrolytic solution that contains an organic solvent having a hydroxyl group, and organic carboxylic acid or a salt thereof. (R-Reach independently represent hydrogen, a hydroxyl group, a cyano group, a nitro group, an amino group, an imino group, a carbonyl group, a carboxyl group, a sulfo group, an aryl group, a 1-8C cycloalkyl group, or a 1-18C alkyl group or alkoxy group which may be branched. R-Rmay together form a ring.)
