  • Imidazoline corrosion inhibitors
    Patent number: 7057050
    Abstract: This invention provides a series of novel acrylated, substituted imidazoline corrosion inhibitors of the formula: 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.
