Description

Tetradecenedisulphonic Acid CAS NO 68003-18-9 is an organic acid surfactant characterized by its long hydrocarbon chain and dual sulfonic acid groups. This molecular structure provides excellent wetting, emulsifying, and dispersing properties, making it a valuable intermediate and functional additive. It is primarily utilized in the formulation of industrial detergents, textile processing aids, and specialty surfactants where strong acid stability and surface activity are required.

Application

• Industrial & Institutional (I&I) Cleaning: Key component in heavy-duty acid cleaners, metal degreasers, and scale removers for its surfactant properties in low pH environments.
• Textile Processing: Acts as a wetting agent, dispersant, and leveling agent in dyeing and finishing processes, particularly for synthetic fibers.
• Surfactant Intermediate: Serves as a crucial building block for synthesizing more complex anionic surfactants, such as sulfonated esters or amides.
• Emulsion Polymerization: Functions as an emulsifier and stabilizer in the production of polymers like acrylics and styrene-butadiene rubber (SBR).
• Oilfield Chemicals: Used in formulations for demulsifiers and drilling fluid additives where tolerance to acidic conditions is necessary.
• Leather Processing: Employed in tanning and dyeing stages as a penetrant and dispersing agent for chemicals.

Quality Control

Our Tetradecenedisulphonic Acid is manufactured under a strict quality management system. Each batch is tested to ensure consistent chemical composition, activity, and performance. Key parameters such as active matter content, acidity, and color are rigorously controlled. A Certificate of Analysis (COA) detailing purity and specific test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its strong acid nature, containers should be made of corrosion-resistant materials like high-density polyethylene (HDPE) or glass-lined steel. Recommended storage temperature is between 15°C and 25°C.
