摘要
The ionic liquid, (IL) 1,1,3,3-tetramethyl-guanidinium lactate, can absorb SO2 from simulated flue gas effectively under ambient conditions (see scheme). Absorbed SO2 can be desorbed under vacuum or by heating, and the IL can be reused. This absorption method might be used for cleaning gases that contain SO2.
