Ionic liquids (ILs) have attracted the scientific community due to several advantages compared with traditional solvents such as their low volatility and high ability to dissolve different organic and inorganic compounds, among other advantages. Transition metals can be toxic compounds; however, this issue can be minimized when used in catalytic amounts which also allows reaction efficiency and selectivity increases. The combination of metal catalysis with the use of ILs can be a powerful tool for several organic reactions, taking advantage of the most attractive property of the ILs, which is the possibility of an easier recycling of the catalytic system, increasing the greenness of the process. The application of ILs in metal-catalyzed oxidation reactions of alcohols and sulfides is discussed in this chapter.

“…Nevertheless, a high oxidant/sulfur rations should to be applied for sulfur removal if there is no catalyst. Many types of the latter, that are able for high sulfur removal at low oxidant/sulfur ratios, molybdenum and Iron catalysts, have been examined by (Mota et al, 2012), (Zhu et al, 2011;Lü et al, 2014) and (Jiang et al, 2014) respectively.…”

The current research paper focuses on the physico-chemical optimization’s parameters for the Microwave Assisted Extractive/ Oxidative Desulfurization (MAEOD) of a real Algerian diesel. The oxidative desulfurization was carried out using vanadyl acetyl acetonate as catalyst, hydrogen pyroxide (30%) as oxidant and an acid Bronsted Ionic Liquid (IL) in situ synthesized as extractor. The utilized optimization method is consistent with the full factorial experiment. The engaged parameters are the masse ratio (catalyst/oil), the volume ratio (IL/oil), and the reaction time. Quantification of total sulfur in samples was realized by X-ray fluorescence and a regression model is formed. The most important model parameters’ interaction effects are examined and the ISO-response curves are outlined in order to simulate the optimal conditions. The optimum yield (81.77%) was achieved during a time radiation of 70 s with a catalyst/oil ratio of 0.4% and IL/oil volume ratio of 11%, with correlation 99.21.
