Vanconol® FPAM-S101 Fatty Acid Aminoethyl Imidazoline Corrosion Inhibitor

🎯 Abstract

Vanconol® FPAM-S101 is a novel high-performance corrosion inhibitor intermediate prepared by directed reaction of fatty acids with polyamines. It features an environmentally friendly, non-toxic profile and is free of heavy metals. Through advanced closed-loop reaction technology, a high cyclization rate is achieved. The imidazoline ring and imino groups in the molecular structure form multi-point anchoring on metal surfaces, providing strong adsorption and building a dense protective film that effectively blocks corrosion reactions. The product can serve as the primary component of high-temperature corrosion inhibitors for oil and gas fields and petrochemical refining applications, and can also be converted through quaternization or functional group modification into a quality raw material for preparing nitrogen-containing cationic surfactants, with applications spanning corrosion protection across multiple industries and fine chemical synthesis.

Water treatment: covers feed water purification, circulating water treatment, cooling water systems, and boiler water treatment, effectively controlling equipment corrosion and hard scale formation (most widely used application).

Petrochemical industry: corrosion control for equipment and pipelines in petroleum processing and chemical production.

Crude oil production: downhole equipment protection, acidizing corrosion control, gathering pipeline and storage tank protection, and water injection system corrosion inhibition.

Steel manufacturing: corrosion protection for equipment and pipelines in steel production processes.

Other industries: corrosion protection and fine chemical applications in power generation, textiles, food processing, and pharmaceuticals.

Product Formulation & Usage

Formulating Water-Soluble Imidazoline Corrosion Inhibitors

Take 10–30 parts of this product based on the total formulation (adjust according to application), and add solvents (e.g., methanol), water, and synergists if necessary.

Start stirring and slowly add acetic acid until the system becomes transparent, maintaining a pH of 6.5–9.

Add amine reagents (e.g., ethylenediamine, triethylamine) to fine-tune the pH to the target value, completing the formulation.

Formulating Oil-Soluble Imidazoline Corrosion Inhibitors

Take 10–30 parts of this product based on the total formulation weight (adjust according to application) and dilute with a suitable solvent.

Add synergists as needed and stir thoroughly until a transparent finished product is obtained.

Usage Precautions

Wear personal protective equipment (gloves, safety goggles, etc.) before handling.

Inspect the material condition before use. If solidification has occurred, immerse in hot water or bake at low temperature to melt before use.

Without synergists, the minimum dosage based on the final working environment (e.g., high-temperature refinery conditions) is 15 ppm. It is recommended to determine the optimal concentration through experimental validation to ensure effective corrosion inhibition.

⚠️ Safety & Storage

Safe Handling

Avoid direct contact with skin and eyes. Wear protective equipment throughout handling.

In case of accidental contact, immediately rinse the affected area with plenty of running water. Seek medical attention if symptoms persist.

Storage & Transportation

Packaging: supplied in plastic drums with a standard net content of 220 L. Custom packaging available upon request.

Storage & transport requirements: protect from sunlight, fire, moisture, and impact. Do not store or transport together with flammable, explosive, or corrosive materials.

Storage environment: keep in a clean, cool, dry, and well-ventilated warehouse, away from ignition sources and heat.

Residual product handling: seal the container promptly after use to prevent evaporation and performance changes.

Shelf life: 12 months under ambient conditions. After the expiry date, re-test performance before use.

❓ FAQ

Q1: Does solidification affect performance?

A1: No. Solidification is a physical state change. After melting by hot water immersion or low-temperature baking, product performance remains unchanged and can be used normally.

Q2: What is the minimum dosage?

A2: Without synergists, the minimum dosage is 10 ppm. The actual dosage depends on the specific application, and laboratory testing is recommended to determine the optimal concentration.

Q3: How do I formulate water-soluble / oil-soluble corrosion inhibitors?

A3: For water-soluble products, use 10–30 parts of this product + solvent + water + acetic acid (adjust pH to 6.5–9) + amine for fine adjustment. For oil-soluble products, use 10–30 parts of this product + solvent + synergist (if needed).

Q4: Can this product be used as a surfactant raw material?

A4: Yes. This product can undergo quaternization or be modified with other functional groups to produce nitrogen-containing cationic surfactants.

Q5: What are the packaging options and shelf life?

A5: Standard packaging is a 220 L plastic container (customizable). Shelf life is 12 months under ambient conditions. Keep sealed after opening.
