Tall Oil Aminoethyl Imidazoline TOAI CAS 61790-69-0 Industrial Water Treatment Corrosion & Scale Inhibitor

Product Overview-Tall Oil Aminoethyl Imidazoline

What is Tall oil aminoethyl imidazoline? 

Tall oil aminoethyl imidazoline is a versatile chemical compound used primarily as a corrosion inhibitor in the oil and gas industry. It is derived from tall oil fatty acids and is known for its strong adsorption properties and thermal stability, making it effective in protecting pipelines, downhole equipment, and storage tanks from corrosion caused by factors like carbon dioxide (CO₂) and hydrogen sulfide (H₂S).

Specification

Application

1. Oilfield Corrosion Inhibitor (Primary Use)TOAI forms a hydrophobic film on metal surfaces, strongly resisting corrosion by HCl, H₂S, CO₂, and high-salinity brines. Downhole & Production: Continuous injection (50–200 ppm) for tubing, casing, and equipment in acidizing, CO₂ flooding, and S-containing wells. Pipelines & Flowlines: 20–100 ppm dosage for internal corrosion control in crude, wet gas, and multiphase lines. Water Injection & Produced Water: Mitigates chloride pitting, oxygen, and microbial corrosion in injection wells and re-injection systems. Storage Tanks & Vessels: Acts as a filming amine for tank bottoms, separators, and heaters. Case Study: In a 15% CO₂ gas well, TOAI-based inhibitor reduced corrosion rates by 85%. 

2. Asphalt EmulsifierAs a cationic emulsifier, it stabilizes asphalt-in-water emulsions for road construction, pavement maintenance, and slurry seals. Provides good adhesion to aggregate. Improves emulsion stability and curing behavior. 

3. Metalworking & Industrial Cleaning Corrosion Inhibitor for Parts: Protects steel, iron, and non-ferrous metals during machining, pickling, and storage. Industrial Detergents & Cleaners: Functions as a surfactant, emulsifier, and wetting agent in alkaline/acidic cleaners, degreasers, and metal cleaners. 

4. Water Treatment Cooling Towers & Recirculating Systems: Inhibits corrosion and scale on carbon steel, copper, and alloy surfaces. Boiler & Feedwater Treatment: Controls oxygen and CO₂ corrosion in boilers and condensate lines. 

5. Paint, Ink & Coatings Additive Printing Inks: Improves pigment dispersion, emulsification, and adhesion; reduces foaming. Coatings & Paints: Acts as a corrosion inhibitor, wetting agent, and dispersant for metal primers and anti-corrosive coatings. 

6. Other Applications Textile Industry: Used as a lubricant, softener, and anti-static agent. Agriculture: Serves as an emulsifier and adjuvant for pesticides and herbicides. Rubber & Plastics: Functions as a dispersant and internal lubricant.
