This invention provides a series of novel acrylated, substituted imidazoline corrosion inhibitors of the formula (I) wherein R1 is an alkyl radical having from 2 to 8 carbon atoms; R2 is a radical derived from a fatty acid; and R3 is a radical derived from an unsaturated acid and a method for inhibiting corrosion in metallic flow lines through the introduction of such inhibitors into a system wherein corrosion is sought to be precluded.
L'invention concerne des inhibiteurs de corrosion acrylés, à substitution imidazoline, de formule (I). R¿1? est un radical alkyle ayant entre 2 et 8 atomes de carbone, R¿2? est un radical dérivé d'un acide gras, et R¿3? est un radical dérivé d'un acide insaturé. On décrit aussi un procédé relatif à l'inhibition de la corrosion pour les conduites d'écoulement métalliques, par l'introduction des inhibiteurs en question dans un système destiné à être protégé contre la corrosion.
