| 摘 要： | 研究了己内酰胺-四丁基溴化铵(CPL-TBAB)离子液体乙醇溶液及其吸收SO2后溶液的pH值、电导率和密度。结果表明:随着温度的增加,CPL-TBAB离子液体乙醇溶液pH值降低,电导率先增加后略微减小,密度降低;随着离子液体浓度的增加,CPL-TBAB离子液体乙醇溶液的pH值先增加后平衡,电导率先增加后降低,密度降低。CPL-TBAB离子液体乙醇溶液吸收SO2饱和后的溶液比吸收前的溶液pH值减小,电导率增加,密度增大,含水量降低,且CPL-TBAB离子液体乙醇溶液吸收SO2后形成共溶体系。

| Abstract: | The pH value,electrical conductivity,density of quaternary ammonium ionic liquids and ethanol solution for absorbing SO2 were researched.The results show that with an increase of temperature,the values of pH decrease,conductivity increase and then decrease slightly,and density decreases.With the increasing concentration of ionic liquids,the values of pH increase and then kept balance,the values of conductivity increase and then decrease slightly,and the values of density decrease.The values of pH and moistu... |
