Conventional acidic catalysts for isobutane and isobutene alkylation exhibit low alkylate selectivity. Herein, we employed an acidic deep eutectic solvent, consisting of trifluoromethanesulfonic acid and taurine, in polyethylene glycol as the catalyst.

Description
Summary:Conventional acidic catalysts for isobutane and isobutene alkylation exhibit low alkylate selectivity. Herein, we employed an acidic deep eutectic solvent, consisting of trifluoromethanesulfonic acid and taurine, in polyethylene glycol as the catalyst. Its high conversion rate and selectivity, as well as recyclability, make it suitable for alkylate gasoline preparation. A [TfOH] 3 [TAU]/PEG-200 catalytic system used for isobutane/isobutene alkylation to prepare alkylate gasoline exhibits excellent C 8 selectivity and recyclability.
