The invention belongs to the technical field of extraction agent synthesis and desulfurization, and specifically discloses a novel deep eutectic solvent simulated gasoline extraction desulfurization method. The specific scheme adopted is: using imidazole and its derivatives and tetrabutylammonium bromide as raw materials, The deep eutectic solvent is synthesized by low-temperature eutectic, then the deep eutectic solvent and simulated gasoline are mixed, stirred at a certain temperature for a certain period of time, the deep eutectic solvent is separated, and the simulated gasoline phase is obtained. The method of the invention has the advantages of simple operation process, low energy consumption, low cost and remarkable effect, and the desulfurization rate can be as high as 95% after four times of extraction. |
