摘要：

In this study, the synthesis and characterization of ionic liquids (ILs) and their application in the extraction of water in water-in-oil (W/O) emulsions are presented. The ionic liquids were used to reduce attractive and repulsive electrostatic interactions at the water-oil interphase, and so to diminish the used energy used during the dehydration process of the crude oil. The ionic liquids were characterized by NMR, FTIR and by electrochemical methods. For the electrochemical characterization, a KCl and 1,2-dichlorobenzene (DCB) medium was used, which allows to know the redox behavior of the ionic liquids and their effect on the conductivity of the addition medium. In addition, through this characterization the effect on the W/O and O/W emulsions were observed, by reducing the resistivity of these and therefore increasing the ionic conductivity.
