In a preferred embodiment, the ionic liquid a is a lipophilic ionic liquid, and the ionic liquid B is a hydrophilic ionic liquid.
As a preferred embodiment, the ionic liquid a is selected from one or more of 1-butyl-3-methylimidazole hexafluorophosphate, 1-butyl-3-methylimidazole bistrifluoromethylsulfonyl imide salt and 1-butyl-3-methylimidazole hexafluoroantimonate.
