Eletrochemical impedance spetroscopy(EIS) studies in ethanol


In mid-1970, Brazil developed technology for the adaption of vehicular engines and for the production of ethanol fuel, achievements that have made the country the pioneer in the use of ethanol as a vehicle fuel. At that time, many research focused their works on metal corrosion by ethanol fuel studies [1-8]. As of 2003, with the development of a bi-fuel car technology (flex fuel) the country received new inputs for ethanol production with a significant increase in its consumption. Within this context, the studies of ethanol fuel began again to have relevance, mainly due to the need of carrying large volume of the product through dedicated pipelines, called ethanol pipelines [9]. This work aims to study the behavior of AISI 1020 carbon steel in anhydrous ethanol from different sources as sugar cane and corn by means of the EIS techniques, using reagent grade anhydrous ethanol as a reference.(Introduction)
