用できなかった。Problems to be Solved by the Invention However, as a conventional problem, when γ-butyrolactone is used as a solvent and triethylamine salt of heptalic acid is used,
Further, when an amine salt of maleic acid was used as a mixed solvent of γ-butyrolactone and ethylene glycol, the specific conductivity was sufficient, but the spark voltage was low and it could only be used at a voltage of 60 V or less.

電解コンデンサ１駆動用電解液である。Means for Solving the Problems In order to solve the above problems, in the present invention, γ-
This is an electrolytic solution for driving the electrolytic capacitor 1, which is made by adding and dissolving hexite and boric acid in a solvent mainly composed of butyrolactone, using a tetramethylammonium salt or tetraethylammonium salt of maleic acid as a solute.
ヘキシットには、ソルビット、マンニット、イジツト、
タリット、ズルシット、アリットがあるが、好ましくは
Ｄ−ソルビット、Ｄ−マンニット。Hexite includes sorbitol, mannitol, iditsu,
There are talit, dulcit, and alit, but D-sorbit and D-mannit are preferred.
ズルシットである。It's Zurshit.
ヘキシットとホウ酸のモル比は通常５：１〜１：６であ
るが、好ましくは２．５ ： １〜１：３である。以上
のモル比の範囲では溶解性にすぐれている。The molar ratio of hexite to boric acid is usually 5:1 to 1:6, preferably 2.5:1 to 1:3. In the above molar ratio range, solubility is excellent.
添加量は電解液重量に基づいて、ヘキシットが１〜１５
％、ホウ酸が１〜１６％である。これは、どちらも１％
未満では火花電圧上昇の効果が小さく、１５％を越える
と比電導度が低下するからである。The amount added is 1 to 15 hexites based on the weight of the electrolyte.
%, boric acid is 1-16%. This is 1% for both
If it is less than 15%, the effect of increasing the spark voltage will be small, and if it exceeds 15%, the specific conductivity will decrease.
作用
γ−ブチロラクトンを主体とする溶媒に、マレイン酸の
テトラメチルアンモニウム塩あるいは、テトラエチルア
ンモニウム塩を溶質として組合わせた場合、高い電導塵
が得られる。この系にヘキシットとホウ素を添加するこ
とによりあまり比電導度を下げずに火花電圧を上げるこ
とができる。Effect When a tetramethylammonium salt or a tetraethylammonium salt of maleic acid is combined as a solute with a solvent mainly composed of γ-butyrolactone, highly conductive dust can be obtained. By adding hexite and boron to this system, it is possible to increase the spark voltage without significantly lowering the specific conductivity.
また、ヘキシットとホウ酸を混合して用いるのはγ−ブ
チロラクトン主体の溶媒の場合、ヘキシット単独あるい
はホウ酸単独では溶解しにくいからである。これらを混
合することにより、溶液中でヘキシットのホウ素鐙体が
でき溶解しやすくなると考えられる。The reason why a mixture of hexite and boric acid is used is that in the case of a solvent mainly composed of γ-butyrolactone, it is difficult to dissolve hexite alone or boric acid alone. It is thought that by mixing these, a boron stirrup of hexite is formed in the solution, making it easier to dissolve.
