Description

Tridecylbenzenesulphonic Acid is a high-purity, synthetic organic acid belonging to the class of alkylbenzenesulfonic acids. This versatile surfactant intermediate is valued for its excellent detergency, wetting, and emulsifying properties in industrial formulations. It serves as a critical raw material for manufacturers in the detergent, agrochemical, and lubricant additive industries seeking to enhance product performance.

Application

• Primary Surfactant Intermediate: Key feedstock for the production of high-performance anionic surfactants, particularly calcium and sodium salts used in industrial and institutional cleaners.
• Detergent & Cleaner Formulations: Essential component in the synthesis of heavy-duty liquid detergents, degreasers, and hard surface cleaners due to its superior oil solubility and cleaning power.
• Emulsifier for Agrochemicals: Used in the formulation of pesticide and herbicide concentrates to ensure stable oil-in-water emulsions for effective crop protection.
• Lubricant & Fuel Additive: Acts as a dispersant and detergent additive in engine oils and industrial lubricants to prevent sludge and varnish formation.
• Textile & Leather Processing: Employed as a wetting agent and penetrant in scouring, dyeing, and tanning processes to improve chemical uptake and uniformity.
• Acid Catalyst: Functions as a strong organic acid catalyst in specific esterification and alkylation reactions within chemical synthesis.

Quality Control

Our Tridecylbenzenesulphonic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for active matter content, free oil, and sulfuric acid levels. A Certificate of Analysis (COA) detailing purity, color, and viscosity is provided with each shipment to guarantee consistency and performance for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture and contamination. Keep away from incompatible materials such as strong bases and oxidizing agents.
