© 2018 The Korean Society of Industrial and Engineering Chemistry SO2 absorption behaviours of N,N-dimethylaniline (DMA), N,N-diethylaniline (DEA), N,N-dibutylaniline (DBA), and N-methyldiphenylamine (MDPA) — were investigated in dry and wet conditions. DMA showed the highest SO2 absorption capacity of 1.5 molSO2 molAbsorbent−1 in dry condition, while DBA showed the highest capacity of 1.75 molSO2 molAbsorbent−1 in wet condition. Raman analyses revealed that anilines captured SO2 by forming charge transfer complexes in dry condition and the interaction between SO2 and aniline decreased as the steric hindrance of alkyl aniline increased. In contrast, bisulfite-based acid-base salt was formed in the presence of water, and the capacity increased with an increasing basicity of the alkyl aniline.
