摘要

Deep eutectic solvents (DESs) 1-butyl-3-methylimidazolium bromide-polyalcohol ([Bmim]Br-polyalcohol) were synthesized from [Bmim]Br and polyalcohol such as ethylene glycol (EG), propylene glycol (PG), glycerol (GL) at a molar ratio of 1:2. [Bmim]Br-2propylene glycol ([Bmim]Br-2PG) was characterized with FT-IR spectroscopy and 1H NMR. The removal of benzothiophene (BT) from model oil was investigated by extraction with DES [Bmim]Br-2PG. The results showed that an extraction efficiency as high as 54.1％ could be achieved with the solvent in one-stage extraction at 30 ℃ in 30 min with a DES/oil mass ratio of 1:1. Deep desulfurization was realized after five-stage extraction, and sulfur content in model oil was reduced to less than 10 μg/g. The used [Bmim]Br-2PG DES was regenerated and showed an extraction efficiency of 50.5％ within four recycles.
