摘要：

N,N-Dibutylundecanolamine is a liquid that chemically binds SO2 to form a viscous zwitterionic liquid that contains 35% by wt. SO2 at standard temperature and pressure. SO2 is chemically bound to the alcohol component as an alkylsulfite, which is then stabilized by the amine. The zwitterionic liquid can be reverted to its non-ionic form and recycled by thermally stripping the SO2 under vacuum at temperatures near 70 degrees C. N,N-Dibutylundecanolamine is a potential flue gas desulfurizing solvent because it is chemically selective to bind SO2 but not basic enough to chemically bind CO2.
