Vanconol® MNC-02 Acidizing Corrosion Inhibitor: Acetophenone Mannich Base Sets a New Standard for Oil and Gas Field Acidizing Corrosion Protection
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. today announced the launch of Vanconol® MNC-02, an acetophenone 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 exhibits outstanding performance under rigorous acidizing conditions.
Breakthrough Solubility in Acid Solutions
The molecular structure of Vanconol® MNC-02 incorporates unique hydrophilic hydroxyl groups, an innovative design that resolves the solubility challenge of conventional Mannich base products in concentrated acids. In high-concentration hydrochloric acid and mud acid systems, the product demonstrates excellent dissolution speed and dispersion uniformity, enabling rapid and homogeneous dispersion without the need for additional surfactants.
According to the SY/T 5405-2019 standard “Test Method and Evaluation Index 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), which is below the required standard value of 6.00 g/(m²·h). This provides reliable corrosion protection for oil and gas field acidizing operations.
Excellent Corrosion Inhibition Performance
Vanconol® MNC-02 is manufactured using a proprietary process that synthesizes molecules with multi-point adsorption structures via the Mannich reaction. Its corrosion inhibition mechanism includes: interaction between the benzene ring π-electron system and the d-orbital of the metal surface to form chemical adsorption anchors; coordination of the lone pair electrons from the carbonyl group (C=O) with iron atoms to enhance adsorption strength; protonation of the tertiary amine group under acidic conditions to form cations that electrostatically adsorb onto the metal surface; and the hydroxyl group providing hydrophilicity to improve solubility in acid solutions.
This unique molecular structure allows the product to form a dense hydrophobic protective film on the metal surface, effectively blocking the attack of corrosive media. Even at high temperatures up to 140°C, the product performs reliably, providing strong support for equipment protection under severe acidizing conditions.
Wide Range of Applications
Vanconol® MNC-02 is suitable for a broad range of applications, including:
Oil and Gas Field Development: Corrosion protection for downhole equipment, refining equipment, gathering 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: Applicable in feed water purification, circulating water treatment, cooling water systems, and boiler water treatment, helping to avoid under-deposit corrosion.
Petrochemical Refining: Serves as a low-temperature corrosion inhibitor in petrochemical refining units to protect equipment from corrosion damage.
Flexible Usage Guidelines
Vanconol® MNC-02 is easy to use. Operators can directly dilute the product with the acidizing solution and stir for 10–15 minutes to achieve homogeneous dispersion. Recommended dosage varies by application: for oil and gas field acidizing (below 90°C) – 0.8%–1.0%; for 90–120°C – 1.5%–2.0%; for industrial cleaning – 0.5%–1.0%; for circulating water treatment – 50–200 ppm.
The product is compatible with various acidizing additives, including iron stabilizers (EDTA, citric acid), clay stabilizers (potassium chloride, polyquaternium), and flowback aids (fluorosurfactants), offering flexibility for custom formulation.
Industry Application Prospects
As oil and gas field development extends to greater depths, acidizing process conditions are becoming increasingly demanding, placing higher requirements on corrosion inhibitor performance. Meanwhile, environmental regulations are tightening, boosting demand for non-toxic, biodegradable corrosion inhibitors. Vanconol® MNC-02, with its excellent solubility in acid solutions, effective corrosion inhibition, and environmentally friendly characteristics, aligns with industry trends and has promising market potential.
