Vanconol® MNC-02 Acidizing Corrosion Inhibitor: Acetophenone Mannich Base Sets a New Standard for Oil and Gas Field Acidizing Corrosion Protection

Tianjin Hi-Perferal Advanced Materials Co., Ltd. is pleased to introduce Vanconol® MNC-02, an acetophenone Mannich base acidizing corrosion inhibitor. This product is a ternary Mannich derivative synthesized from acetophenone as the starting material, with an effective solid content of 50%, demonstrating outstanding performance under demanding acidizing conditions.

Breakthrough Acid Solubility

The molecular structure of Vanconol® MNC-02 incorporates a unique hydrophilic hydroxyl group, an innovative design that overcomes the poor solubility of conventional Mannich base products in concentrated acids. In high-concentration hydrochloric acid and mud acid (HCl-HF) systems, the product exhibits exceptional dissolution rate and dispersion uniformity, achieving rapid and homogeneous dispersion without the need for additional surfactants.

According to the SY/T 5405-2019 standard, “Test Methods and Evaluation Criteria for Corrosion Inhibitors Used in Acidizing,” under conditions of 90°C and 20% hydrochloric acid, the measured corrosion rate is only 5.2 g/(m²·h), below the standard requirement of 6.00 g/(m²·h), providing reliable corrosion protection for oil and gas field acidizing operations.

Superior Corrosion Inhibition Performance

Vanconol® MNC-02 is produced via a proprietary process, utilizing the Mannich reaction to synthesize molecules with a multi-site adsorption structure. Its corrosion inhibition mechanism includes: the benzene ring π-electron system interacting with the metal surface d-orbitals to form chemisorption anchor points; the lone pair electrons of the carbonyl group (C=O) coordinating with iron atoms on the metal surface, enhancing adsorption strength; the tertiary amine group protonating under acidic conditions to form cations that adsorb electrostatically onto the metal surface; and the hydroxyl group providing hydrophilicity, improving solubility in acid solutions.

This unique molecular architecture enables the product to form a dense, hydrophobic protective film on the metal surface, effectively blocking corrosive media from attacking the metal substrate. Even at elevated temperatures up to 140°C, the product maintains excellent performance, offering robust protection for equipment under severe acidizing conditions.

Broad Application Areas

Vanconol® MNC-02 boasts a wide range of applications, including:

Oil & Gas Field Development: Used for corrosion protection of downhole equipment, refining facilities, gathering and transmission pipelines, and storage tanks, extending equipment service life and reducing maintenance costs.

Industrial Cleaning: Effectively prevents over-acid corrosion during acid cleaning processes, protecting the base metal from damage.

Water Treatment: Suitable for feed water purification, circulating water treatment, cooling water systems, and boiler water treatment, effectively mitigating under-deposit corrosion.

Petrochemical Refining: Serves as a low-temperature corrosion inhibitor for refining units, protecting equipment from corrosion damage.

Flexible Application Guidelines

Vanconol® MNC-02 is easy to use; operators simply dilute the product directly with the acidizing fluid and stir for 10-15 minutes to achieve uniform dispersion. Recommended dosage varies by application: for oil and gas field acidizing (below 90°C), a dosage of 0.8%-1.0% is suggested; (90-120°C), 1.5%-2.0% is recommended; for industrial cleaning, 0.5%-1.0% is advised; and for circulating water treatment, 50-200 ppm is recommended.

The product exhibits good compatibility with various acidizing additives, including iron stabilizers (EDTA, citric acid), clay stabilizers (potassium chloride, polyquaternary ammonium salts), and non-emulsifying agents (fluorosurfactants), offering users flexibility in formulation customization.

Industry Application Outlook

As oil and gas field development extends to greater depths, acidizing process conditions become increasingly severe, imposing higher demands on corrosion inhibitor performance. Simultaneously, tightening environmental regulations are driving the demand for non-toxic, biodegradable corrosion inhibitors. With its excellent acid solubility, efficient corrosion inhibition performance, and comprehensive environmentally friendly characteristics, Vanconol® MNC-02 aligns with industry development trends and holds broad market prospects.
