DESULFURIZATION OF HYDROCARBONS BY IONIC LIQUIDS AND PREPARATION OF IONIC LIQUIDS.

摘要

The present invention relates to the synthesis by microwave heating of 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, FeCl4-. The ionic liquids can be used to desulfurize hydrocarbon mixtures by a liquid-liquid extraction.
