Abstract: The present invention relates to the application of ionic liquids individually or in formulation to dry and desalt crudes oils having API gravities in the range of 8 to 12 (median, heavy and extra-heavy) when applied at concentrations ranging from 500 and up to 5000 ppm. The ionic liquids have a cation selected from the group consisting of carboxymethane-ammonium, ammonium, imidazolium, isoquinolinium, pyridinium, and 1,5-dicarboxylic-pentane-2-ammonium and an anion selected from the group consisting of R5COO?, Cl?, Br?, [BF4]?, [PF6]?, [SbF6]?, [R6SO4]?, [OTs]31 , [OMs]?, where R5 is alkyl, cycloalkyl, benzyl, alkenyl, aromatic or alkyl functionalized between 1 and 18 carbon atoms, and R6 is methyl or ethyl.
