Separation performance of TpPa/PI membrane in relation to catalysts compared with those of other OSN membranes in the literature [31,32,33].
| Membrane | Catalyst | Solvent | Solvent Permeance (LMH/MPa) |
Catalyst Rejection (%) | Reference |
|---|---|---|---|---|---|
| TpPa/PI | Jacobson’s catalyst | Ethanol acetate | 75.8 | 87.1% | This work |
| COK M2 | Jacobson’s catalyst | Ethyl ether | 2.2 | 83.0% | [31] |
| DuraMem 300 | Magnesium trifluoromethanesulfonate | Ethanol/Ethyl acetate/Cyclohexane | 1.0 | 98.0% | [32] |
| PERVAP 4060 | Tetraoctylammonium bromide | Toluene | 20.0 | 92.0% | [33] |
