Abstract
This invention provides a series of novel acrylated, substituted imidazoline corrosion inhibitors of the formula: 1 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.
Claims19
An imidazoline corrosion inhibitor of the formula
- 4
- 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.
An imidazoline corrosion inhibitor selected from the group consting of
- N-propyl-2-heptadecenyl imidazoline acrylate,
- N-butyl-2-heptadecenyl imidazoline acrylate and
- N-hexyl-2-heptadecenyl imidazoline acrylate.
A method for inhibiting corrosion in metallic lines comprising adding to the fluid contained in the flow line a corrosion inhibiting amount of a water-soluble substituted imidazoline having the formula:
- 5
- 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.
