由于超氧阴离子在质子的存在下很容易分解，人们知道超氧阴离子只溶解在特定的高极性非质子溶剂中，如二甲基亚砜。有机溶剂因其高挥发性和易燃性而具有危险性，而离子液体具有易燃性、不挥发性和高离子导电性。此外，在有机合成领域，有可能出现一种不同于现有有机反应介质的新反应介质。因此，离子液体作为一种新的反应介质和电池电解液具有很大的吸引力。在本研究中，我们研究了超氧阴离子在五种离子液体中的溶解度和稳定性。结果表明，从超氧阴离子的溶解度和稳定性来看，P14、6、6、6Cl是最合适的溶剂。
Because superoxide anion is easily decomposed by the presence of proton, it is known that superoxide anion only dissolves in specific highly polar aprotic solvents such as dimethylsulfoxide. Organic solvents are dangerous due to their high volatility and flammability, while ionic liquids possess inflammability, nonvolatility, and high ion conductivity. Additionally, in the area of organic synthesis, there is a potential for a new reaction media different from existing organic reaction media. Therefore, it would be attractive to use ILs as a new reaction media and an electrolyte of batteries. In this study, we studied solubility and stability of superoxide anion in five kinds of ILs. It was found that P14, 6, 6, 6Cl was the most suitable solvent in terms of the solubility and stability of superoxide anion.
