Abstract

A tungsten-containing task-specific ionic liquid (IL) [(C6H13)3PC14H29]2W6O19 was synthesized and applied in the desulfurization process of a dibenzothiophene-containing model oil with aqueous hydrogen peroxide. In the desulfurization process, a novel aqueous hydrogen peroxide-in-IL emulsion catalytic system was found. The task-specific IL not only acted as extraction media for the organo-sulfur compounds and served as a catalyst for the hydrogen peroxide but also provided an oxidation micro-environment for the conversion from sulfur compounds to sulfones by forming IL emulsions. The self-emulsifiable IL played two roles in the emulsification process: the surfactant and the dispersion medium.
