合成了一种含钨功能化离子液体[(C6 H13)3 PC 14 H29] 2 W 6 O 19,并将其应用于含二苯并噻吩模型油的H2 O2脱硫过程。在脱硫过程中,发现了一种新型的过氧化氢-IL乳状液催化体系,该体系不仅可以作为有机硫化合物的萃取介质和过氧化氢的催化剂,而且可以通过形成IL乳状液为含硫化合物转化为砜类化合物提供氧化微环境。自乳化离子液体在乳化过程中起两种作用:表面活性剂和分散介质。
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.
