Abstract

In the present work, the ionic liquid (IL) N-dimethyl-N-di(cocoalkyl) ammonium methyl sulfate (DCA) was tested as a corrosion inhibitor (CI). The tests were carried out in 1 M solutions of hydrochloric acid (HCl) in order to inhibit the corrosion of API 5L X-52 steel. The maximum inhibition efficiency (IE) was obtained at 4 h and 50 °C within the 96-99% interval and IE was obtained at 0 h and 30 °C within the 50-94% interval. The tests indicated that DCA inhibited the steel corrosion and worked as a mixed-type inhibitor, where the molecular adsorption on steel was described by the Langmuir isotherm, whereas thermodynamics suggested that a physisorption process occurred.
