TOFA-DETA Imidazoline| CAS 61790-69-0

Description

TOFA-DETA Imidazoline (CAS: 61790-69-0) is an oil-soluble imidazoline corrosion inhibitor synthesized by high-temperature vacuum cyclization reaction of renewable tall oil fatty acid (TOFA) and diethylenetriamine (DETA). Rich in imidazoline heterocyclic tertiary amine groups, it forms a compact hydrophobic protective film on carbon steel surfaces, delivering outstanding anti-corrosion performance against H₂S, CO₂ and saline formation water, specially developed for upstream oil & gas field corrosion control.

Key Advantages

1. High-efficiency Corrosion Resistance: Abundant imidazoline tertiary amine structure realizes strong chemisorption on steel, long-lasting inhibition under high-temperature sour oilfield working conditions.
2. Excellent Oil Solubility: No stratification or precipitation in high water-cut crude oil systems, suitable for continuous injection anti-corrosion processes.
3. Renewable Raw Material Base: Derived from sustainable pine-based TOFA, eco-friendly and partially biodegradable.
4. Stable Formula Consistency: Controlled vacuum cyclization process guarantees stable tertiary amine index batch by batch, easy for downstream formulation compounding.
5. Cost Competitive: Ideal substitute for high-priced imported imidazoline corrosion inhibitor raw materials.
