Ionic liquid, RTIL, pollution control, absorber, Henry's Law constant


The capture of organic compounds from the exhaust gases of dryers and presses in the wood products industry is difficult due to low concentrations and high gas volumes. The possibility of using room temperature ionic liquids as absorbents was investigated by determining the Henry's Law constants for methanol and α-pinene in four imidazolium-based and eight phosphonium-based ionic liquids. The stability of the imidazolium-based ionic liquids proved problematic. The constants for the phosphoniumbased ionic liquids were low, indicating that the ionic liquids tested might be very good absorbents.
