Description

Benzenesulfonic Acid, Mono-C16-24-Alkyl Derivs., Barium Salts, Overbased is a specialized organometallic compound primarily used as a high-performance detergent and acid neutralizer in lubricant formulations. Its overbased structure provides exceptional reserve alkalinity, making it critical for protecting engine components against corrosive wear and deposit formation. This product is essential for formulators in the automotive and industrial lubricant industries seeking to enhance the longevity and performance of engine oils, gear oils, and greases.

Application

• Primary Detergent Additive in engine oils (passenger car and heavy-duty diesel) to control sludge, varnish, and deposits.
• Acid Neutralizer in lubricating oils and greases, neutralizing acidic by-products of fuel combustion and oil degradation.
• Component in Marine Cylinder Oils for large two-stroke engines, managing corrosive sulfuric acid from high-sulfur fuels.
• Additive for Industrial Gear Oils and Hydraulic Fluids to improve cleanliness and thermal stability.
• Performance Enhancer in Grease Formulations, contributing to thickening and corrosion inhibition.
• Ash-Containing Detergent in lubricant additive packages, often blended with other components like dispersants and anti-wear agents.

Quality Control

Our Benzenesulfonic Acid, Mono-C16-24-Alkyl Derivs., Barium Salts, Overbased is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as Total Base Number (TBN), barium content, viscosity, and sulfated ash are rigorously tested. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
