Abstract:Ionic liquids (ILs) show great potential for the treatment
of dichloromethane
(DCM)-containing waste gases, but currently there are limited data
on the vapor–liquid equilibrium (VLE) of DCM + IL systems.
This work uses headspace gas chromatography (HS-GC) to determine the
isothermal VLE data of the DCM + [Epy][EtSO4] and DCM +
[Emim][EtSO4] systems at 308.15 K, 313.15 K, 318.15 K,
323.15 K, and 328.15 K. The nonrandom two-liquid (NRTL) and universal
quasi-chemical correlation activity coefficient (UNIQUAC) mod… Show more
