摘要：
We report the performance of multiple CO2 binding organic liquids (CO(2)BOLs) as solvent systems for post combustion gas capture. Alkanolguanidines and alkanolamidines are single component CO(2)BOLs that reversibly bind CO2 chemically as liquid zwitterionic amidinium/guanidinium alkylcarbonates. Select alkanolguanidines/alkanolamidines and guanidine/alcohol mixtures were tested for CO2 capacity and solvent lifetime. Solvent performance of these three CO(2)BOLs was assessed by batchwise CO2 uptake and release over multiple cycles. We report each CO2BOL's activity and solvent durability with and without water.
