Description

Dodecylbenzenesulfonic Acid is a key organic sulfonic acid widely utilized as a versatile intermediate and surfactant precursor. Its high reactivity and surfactant properties make it an essential building block in the formulation of detergents and industrial cleaning agents. This product is critical for manufacturers in the chemical synthesis, agrochemical, and personal care industries seeking a reliable raw material for sulfonation reactions and emulsification.

Application

• Primary raw material for the production of linear alkylbenzene sulfonate (LAS) surfactants, a major component in household and industrial detergents.
• Intermediate in the synthesis of emulsifiers and wetting agents for agrochemical formulations such as herbicides and pesticides.
• Acid catalyst in various organic synthesis and esterification reactions within specialty chemical manufacturing.
• Key ingredient in the formulation of industrial and institutional (I&I) cleaning products and degreasers.
• Used in the production of oil-soluble petroleum sulfonates for applications in enhanced oil recovery and lubricant additives.
• Precursor for sulfonated resins and polymers in certain material science applications.

Quality Control

Our Dodecylbenzenesulfonic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. The product undergoes comprehensive analytical testing, including assay, acidity, and color determination, to meet precise customer specifications. A Certificate of Analysis (COA) documenting all critical parameters is provided with each shipment to guarantee compliance with your 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 hygroscopic (moisture-sensitive) and strong acid nature, the container must be kept tightly sealed to prevent moisture absorption and corrosion. Recommended storage temperature is between 15°C and 25°C.
