摘要: Abstract Molecular dynamics simulations of solutions benzene in dimethylimidazolium chloride and hexafluorophosphate have been performed with a view to answering the question posed title. The difference between chemical potential normal model one no charges was found depend on solvent but is at least 4 kBT. This sufficient account for observed solubility differences. There are substantial changes local structure around without charges.
