Effective Absorption of Dichloromethane Using Carboxyl-Functionalized Ionic Liquids.

ABSTRACT: Dichloromethane (DCM) is recognized as a very harmful air pollutant because of its strong volatility and difficulty to degrade. Ionic liquids (ILs) are considered as potential solvents for absorbing DCM, while it is still a challenge to develop ILs with high absorption performances. In this study, four carboxyl-functionalized ILs-trioctylmethylammonium acetate [N₁₈₈₈][Ac], trioctylmethylammonium formate [N₁₈₈₈][FA], trioctylmethylammonium glycinate [N₁₈₈₈][Gly], and trihexyl(tetradecyl)phosphonium glycinate [P₆₆₆₁₄][Gly]-were synthesized for DCM capture. The absorption capacity follows the order of [P₆₆₆₁₄][Gly] > [N₁₈₈₈][Gly] > [N₁₈₈₈][FA] > [N₁₈₈₈][Ac], and [P₆₆₆₁₄][Gly] showed the best abs
