Beschreibung
Zusammenfassung:	The invention provides a composition comprising a corrosion inhibitor, and a corrosion inhibitor intensifier composition comprising an intensifier compound that corresponds to the following formula (I): wherein R1 is a methyl or ethyl group, and R2 is H or an alkyl, aryl, alkyl aryl, alkylthio aryl, alkyloxy aryl, halogenated aryl, phenyl, alkyl phenyl, alkylthio phenyl, alkyloxyphenyl, or a halogenated phenyl group. The invention also provides a method comprising: contacting a metal surface with an acidic fluid comprising an aqueous base-fluid, an acid, and the corrosion inhibitor composition. Cette invention concerne une composition comprenant un inhibiteur de corrosion, et une composition d'intensification d'inhibiteur de corrosion comprenant un composé intensificateur qui correspond à la formule (I) ci-après, où R1 représente un groupe méthyle ou éthyle, et R2 représente H ou un groupe alkyle, aryle, aralkyle, aralkylthio, aryl-alkoxy, haloaryle, phényle, phénalkyle, alkylthiophényle, alkyloxyphényle, ou un groupe halophényle. L'invention concerne également un procédé comprenant l'étape consistant à mettre en contact une surface métallique avec un fluide acide comprenant un fluide de base aqueux, un acide et la composition d'inhibiteur de corrosion.
