Oxidative Desulfurization Catalyzed by Molybdophosphate-Based Ionic Liquid

Abstract

Abstract: Oxidative desulfurization of dibenzothiophene and other sulfides in ionic liquid for model oil was investigated over molybdophosphate-based ionic liquid [hmim]₃PMo₁₂O₄₀. Under the mild conditions, high desulfurization was obtained for dibenzothiophene (90%) and dialkyl sulfides (100%). The effects of catalyst, reaction temperature, and amount of H₂O₂ were investigated. The ionic liquid can be recycled 4 times without a significant decrease in activity.

Key words: molybdophosphate-based ionic liquid, dibenzothiophene, hydrogen peroxide, oxidative desulfurization
