The resultant Ch-ILs were applied in the CO2capture,and their CO2absorption capacities are shown in Table 1.Obviously,each Ch-IL has CO2absorption capacity higher than1.0 mol per mol IL,suggesting the strong interaction between the IL and CO2,which probably originated from the chemical absorption by the IL.In contrast,the CO2capacity of each Ch-IL was significantly greater than that of triethylene glycol dimethyl ether(0.14 mol/mol).To explore the influences of temperature and pressure on the CO2capacities,the CO2adsorption capacities of these ILs were examined in the temperature range of 30–60°C at 1 atm,and in the pressure range of 0.3–1 atm at 30°C,respectively,as shown in Tables S1 and S2(Supporting Information online).It is obvious that both temperature and pressure have a little influence on the CO2adsorption capacity,deduced from the facts that the CO2absorption capacity decreased slightly with the temperature,and increased slightly with the pressure under the experimental conditions.
