The present invention relates to an improved desulfurization process using an ionic liquid compound of general formula C + A − , where C + represents an organic cation such as alkyl-pyridinium, di-alkyl imidazolium and tri-alkyl imidazolium; and A − is an anion of halides of iron (III), such as, for example, FeCl 4 − . The desulfurization process is also improved when producing the ionic liquid compound by heating the reactants using microwave energy. The ionic liquids can be used to desulfurize hydrocarbon mixtures by a liquid-liquid extraction. |
