Vanconol FPI-S101MT Fatty Acid Polyamine Imidazoline Corrosion Inhibitor

Vanconol® FPI-S101MT Corrosion Inhibitor

(Fatty Acid Polyamine Imidazoline)

1 🎯 Abstract

This product is a new type of high-efficiency corrosion inhibitor intermediate prepared by the precise reaction of fatty acid aminoethyl imidazoline and thiourea, featuring core characteristics of environmental friendliness, non-toxicity, and no heavy metals. It exhibits excellent corrosion inhibition performance for acid corrosion scenarios in medium pH environments. Relying on advanced ring-closing reaction technology, it achieves a high cyclization rate of ≥83%. The imidazoline ring and imino group in the molecular structure can form multi-point anchoring with the metal surface, strongly adsorbing and constructing a dense and stable protective film to block corrosion reactions at the source. This product can be used as a high-quality raw material for formulating oil and gas field corrosion inhibitors and petrochemical refining high-temperature corrosion inhibitors. Meanwhile, it is compatible with the formulation requirements of water-soluble and oil-soluble products, and is widely applied in anti-corrosion scenarios of various industries such as water treatment, petrochemical industry, and iron and steel manufacturing.

3.2 Usage Methods and Recommended Dosage

3.2.1 Formulation of Water-Soluble Imidazoline Corrosion Inhibitor

Take 10-30 parts of this product based on the total formula (adjust dosage according to specific purposes), add solvent (such as methanol), water, and add synergists as needed;

Start stirring, slowly add acetic acid until the system is completely transparent, and control the pH value in the range of 6.5-9;

Add amine reagents (such as ethylenediamine, triethylamine, etc.) to fine-tune the pH to the target requirement, and stir evenly before use.

3.2.2 Formulation of Oil-Soluble Imidazoline Corrosion Inhibitor

Take 10-30 parts of this product based on the total formula (adjust dosage according to specific purposes), and add suitable solvents for dilution;

Add synergists as needed, and stir until the system becomes a transparent liquid to complete the formulation.

3.2.3 Operation and Dosage Recommendations

Personal protective equipment (such as protective gloves, goggles, etc.) must be worn before operation to avoid direct contact with skin and eyes;

Check the material state in the barrel before use. If solidification occurs, pre-melt it (recommended by hot water immersion or low-temperature baking < 80℃), and use it after complete melting to ensure uniform product performance;

The formulation dosage of this product needs to be adjusted according to different application scenarios (10-30 parts). It is recommended to verify the appropriate concentration through experiments during actual use to achieve the ideal corrosion inhibition effect.

4 ⚠️ Safety and Storage

4.1 Safe Operation

Wear personal protective equipment throughout the process to avoid direct contact of materials with skin, eyes and respiratory tract;

If it comes into contact with skin or eyes accidentally, immediately rinse with a large amount of flowing water for at least 15 minutes, and seek medical attention if symptoms persist;

The operation site must be well-ventilated, away from fire sources and flammable and explosive substances.

4.2 Storage and Transportation

Packaging Specifications: Packaged in iron barrels with a standard net content of 220L; other packaging forms can be customized according to user's actual needs;

Storage and Transportation Requirements: Strictly protect from sunlight, fire, moisture and collision during storage and transportation; it is strictly prohibited to store and transport with corrosive, flammable and explosive substances;

Storage Environment: Should be stored in a clean, cool, dry and well-ventilated warehouse, away from heat sources and fire sources, and avoid direct sunlight;

Handling of Remaining Products: After use, the barrel mouth must be sealed in time to prevent product volatilization or moisture absorption, which will affect performance stability;

Shelf Life: Under normal temperature (around 25℃) and sealed storage conditions, the product shelf life is one year. After expiration, it is recommended to re-test the core performance indicators before use if qualified.

5 ❓ Frequently Asked Questions (FAQ)

Q1: Will the product's performance be affected after solidification?

A1: No. Solidification is a physical state change that does not alter the chemical properties of the product. After complete melting by hot water immersion or low-temperature baking < 80℃, the product performance remains stable and can be formulated and used normally.

Q2: For which corrosion scenarios is this product more effective?

A2: This product has a targeted corrosion inhibition effect on acid corrosion in medium pH environments, and can also exert efficient protection effects in conventional anti-corrosion scenarios (such as equipment and pipeline corrosion).

Q3: What are the core differences between the formulation of water-soluble and oil-soluble imidazoline corrosion inhibitors?

A3: Water-soluble products need to add water, acetic acid (adjust pH to 6.5-9) and amine reagents to ensure the system is transparent; oil-soluble products only need to be diluted with solvents and add synergists as needed, without pH adjustment.

Q4: What does the non-volatile matter content ≥97% mean?

A4: High non-volatile matter content indicates high concentration of active ingredients in the product, which makes the dosage more accurate during formulation, the corrosion inhibition effect more stable, and reduces waste and environmental impact caused by solvent volatilization.

Q5: How to extend the shelf life of the product after opening?

A5: After opening, the barrel mouth must be sealed immediately, stored in a cool, dry and well-ventilated warehouse to avoid moisture absorption, volatilization or contamination, and ensure use within the shelf life; if expired, core indicators such as cyclization rate and corrosion inhibition performance need to be tested before use if qualified.
