PYRIDINIUM-BASED IONIC LIQUIDS APPLIED IN HYDROCARBON DESULFURIZATION AND THE SYNTHESIS THEREOF WITH ULTRASOUND.

摘要

The present invention is related to the use of ionic liquids and the synthesis effect originated by the ultrasound heating of the ionic liquid components of general formula C*A-, where C* represents a heterocyclic cation of the organic type, specifically of the alkyl-pyridinium, di-alkyl-pyridinium and tri-alkyl-pyridinium type; while the anion A is a derivative of halides, iron halides (III), aluminum halides, zinc halides, copper halides, tin halides, di-halides of iron and di-halides of aluminum, over the desulfurization process of the fuels derived from oil by means of a liquid-liquid extraction.
