Imidazoline Corrosion Inhibitor for Oil Wells
CAS Number: 27136-73-8
Imidazoline-based corrosion inhibitor is a nitrogen-containing heterocyclic compound widely used to protect steel surfaces in oil and gas production against CO₂, H₂S, and organic acid corrosion. It forms a protective adsorbed film on metal surfaces, achieving corrosion protection efficiency above 95% in harsh sour and sweet service conditions. Suitable for use in production tubing, pipelines, and surface facilities.
