Figure 6. Equilibrated snapshots of DESs distributions with different concentrations at acid/hydrocarbons interface. (a), (b), and (c) ChCl-Pho (1:2) at 1.0 wt%, 3.0 wt%, and 5.0 wt%, respectively. (d), (e), and (f) ChCl-TsOH (1:1) at 1.0 wt%, 3.0 wt%, and 5.0 wt%, respectively. (g), (h), and (i) ChCl-BOA (1:2) at 1.0 wt%, 3.0 wt%, and 5.0 wt%, respectively.
Green color represents the H2SO4molecules in line style. Blue color represents isobutane molecules in VDW style. Brown color means 2-butene molecules in VDW style.
