Resumo: Light petroleum derivatives consist of nonpolar hydrocarbons, which are aggressive to carbon steel due to the presence of water. In this study, we show both experimentally and theoretically that the water-phase pH during corrosion is controlled by the interaction of the aqueous phase with the atmospheric CO2 and with iron corrosion products in both solution and precipitates. During the corrosion process, the pH of the solution changes, regardless of its initial value, towards a neutral value. This behaviour explains why the corrosiveness of a petroleum derivative emulsion is not influenced by the initial water-phase pH.
