However, when an amine salt of manic acid was used in 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 for voltages below 50V.

This is an electrolytic solution for driving an electrolytic capacitor, which is made by adding and dissolving hexite and boric acid in a solvent mainly composed of butyrolactone, with tetramethylammonium salt or tetraethylammonium salt of phthalic acid as a solute.
ヘキシットには、ゾルピット、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−ゾルピット、Ｄ−マンニット、ズルシットである。Hexit includes solpit, mannit, ijitut,
There are talit, dulcit, and alit, and D-solpit, D-mannit, and dulcit are preferred.
ヘキシットとホウ酸のモル比は通常６：１〜１：５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 6:1 to 1:5, 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
係、ホウ酸が１〜１５％である。これは、どちらも１チ
未満では火花電圧上昇の効果が小さく、１６％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.
The content of boric acid is 1 to 15%. This is because if both are less than 1%, the effect of increasing the spark voltage is small, and if it exceeds 16%, the specific conductivity decreases.

できる。Function: When a solvent mainly composed of T-butyrolactone is combined with a tetramethylammonium salt or a tetraethylammonium salt of phthalic acid as a solute, high conductivity can be obtained. By adding hexite and boric acid to this system, it is possible to increase the spark voltage without significantly lowering the specific conductivity.

混合することにより、溶液中でヘキシットのホウ素錆体
ができ溶解しやすくなると考えられる。It's a waste to use a mixture of hexite and boric acid.
This is because it is difficult to dissolve hexite alone or boric acid alone in the case of a solvent mainly composed of butyrolactone. It is thought that by mixing these, a boron rust body of hexite is formed in the solution and becomes easier to dissolve.
