TOFA-DETA Imidazoline in Oilfield Chemicals
TOFA-DETA Imidazoline is a core tall oil-based imidazoline intermediate, widely adopted in modern oilfield chemical formulations. Synthesized from tall oil fatty acid (TOFA) and diethylenetriamine (DETA), it features natural biodegradability, zero organic chloride, and stable corrosion inhibition performance, making it a mainstream material for compliant, eco-friendly oilfield chemicals across global oil and gas operations, especially Russia and CIS oilfields.
Core Properties
TOFA-DETA Imidazoline differs from synthetic imidazoline products, relying on natural tall oil fatty acid molecular structures to deliver unique technical advantages. Tested per OECD 301B standards, Tall Oil-Based Imidazoline exhibits high biodegradability, low aquatic toxicity, and no persistent environmental residue. The product maintains stable imidazoline ring content, low free amine, and consistent batch quality, with zero organic chloride (zero XOC), fully complying with strict oilfield chemical environmental regulations.
Unlike saturated synthetic imidazoline, TOFA-DETA Imidazoline adapts well to low-temperature northern oilfield environments, solving the problem of poor natural degradation of traditional oilfield additives in produced water and sediment systems.
Oilfield Environmental Compliance Value
Key Oilfield Applications
TOFA-DETA Imidazoline balances excellent filming anticorrosion performance and environmental adaptability, suitable for multiple core oilfield chemical formulations:
- Filming-type oilfield corrosion inhibitors: TOFA-DETA Imidazoline forms dense protective films on carbon steel surfaces, effectively resisting CO₂ sweet corrosion and moderate H₂S sour corrosion in downhole tubulars and oil/gas pipelines
- Low-temperature resistant pipeline anticorrosion agents: Stable activity in low-temperature environments, ideal for West Siberian and northern cold-region oilfield operations
- Eco-friendly produced water treatment additives: High biodegradability reduces post-treatment pressure and meets discharge environmental standards
- Green acidizing corrosion inhibitors: Low toxicity and high inhibition efficiency for oil well acidizing construction scenarios
- Oilfield emulsifier intermediates: Used in the formulation of asphalt emulsifiers and low-pollution oilfield surfactants
