Table 2. Summary of Recycling Performance with Different Methodsa.
| ILM | AAA in batch | AAA in flow | |
|---|---|---|---|
| BMIM-OTf Recovery Rate (v/v, %) | 50.5 | 87.0 | 78.6 |
| BMIM-NTf2 Recovery Rate (v/v, %) | N.A. | 90.8 | 87.3 |
| Water Conc. in Re. BMIM-NTf2 (wt%) | N.A. | 4.9 | 2.2 |
Recovery rates are presented in volumetric ratios. Water concentrations in recycled BMIM-NTf2 are presented in weight percentages. Recovery rate and water concentration are unavailable in the ILM method due to process difference.
