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

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

Tianjin Hi-Perferal Advanced Materials Co., Ltd. today announced the launch of Vanconol®MNC-02, an acetophenone-based Mannich base acidizing corrosion inhibitor. This product is a ternary Mannich derivative modified from acetophenone as the starting material, with an active content of 50%. It delivers reliable performance under severe acidizing conditions.

Breakthrough Acid Solubility

The molecular structure of Vanconol®MNC-02 incorporates unique hydrophilic hydroxyl groups, an innovative design that resolves the poor solubility of conventional Mannich base products in concentrated acids. In high-concentration hydrochloric acid and mud acid systems, the product exhibits fast dissolution and uniform dispersion without requiring additional surfactants.

According to SY/T5405-2019 “Test Method and Evaluation Index of Corrosion Inhibitors for Acidizing,” under conditions of 90°C and 20% HCl, 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 acidizing operations.

Excellent Corrosion Inhibition Performance

Vanconol®MNC-02 is synthesized via a Mannich reaction using a proprietary process, producing molecules with multi-point adsorption structures. The inhibition mechanism includes: interaction between the benzene ring π-electron system and the d-orbitals of the metal surface to form chemisorption anchors; coordination of lone-pair electrons from the carbonyl (C=O) group with iron atoms, enhancing adsorption strength; protonation of the tertiary amine group under acidic conditions to form cations for electrostatic adsorption on the metal surface; and hydroxyl groups providing hydrophilicity to improve solubility in acid solutions.

This unique molecular structure enables the product to form a dense hydrophobic protective film on the metal surface, effectively blocking corrosive attack from the medium. Even at high temperatures up to 140°C, the product performs well, offering strong support for equipment protection under severe acidizing conditions.

Wide Application Areas

Vanconol®MNC-02 covers a broad range of applications:

Oil & gas field development: corrosion protection for downhole equipment, refinery equipment, gathering pipelines, storage tanks, etc., 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 systems, and boiler water treatment, helping avoid under-deposit corrosion.

Petrochemical refining: serves as a low-temperature corrosion inhibitor for petrochemical refining, protecting refinery units from corrosion damage.

Flexible Usage 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 & gas acidizing (below 90°C), a dosage of 0.8%–1.0% is recommended; (90–120°C), 1.5%–2.0%; for industrial cleaning, 0.5%–1.0%; for circulating water treatment, 50–200 ppm.

The product shows good compatibility with various acidizing additives, including iron ion stabilizers (EDTA, citric acid), clay stabilizers (potassium chloride, polyquaternary ammonium salts), and flowback aids (fluorosurfactants), offering flexibility for custom formulation.

Industry Application Outlook

As oil and gas development extends to deeper formations, acidizing conditions become more demanding, requiring higher corrosion inhibitor performance. Meanwhile, increasingly stringent environmental regulations drive demand for non-toxic, biodegradable corrosion inhibitors. Vanconol®MNC-02, with its excellent acid solubility, efficient corrosion inhibition, and overall environmental profile, aligns with industry trends and has broad market potential.
