Applications
1. For Surfactant & Detergent Production: Dodecylbenzene (CAS 123-01-3) is the key feedstock for producing dodecylbenzene sulfonic acid (DDBSA) and linear alkylbenzene sulfonate (LAS), the widely used anionic surfactant for laundry detergents, dishwashing liquids and industrial cleaning formulations.
2. For Transformer & Cable Insulating Oil: Dodecylbenzene is used as an insulating oil for transformers, cables and capacitors, providing good dielectric properties, low pour point and thermal stability in electrical power applications.
3. For Heat Transfer Fluids: As a thermally stable hydrocarbon, dodecylbenzene serves as a heat transfer fluid in industrial heating and cooling systems, supporting efficient thermal management in processing applications.
4. For Lubricant & Specialty Fluids: Dodecylbenzene is a component in specialty lubricant base stocks and functional fluids, providing low-temperature performance and oxidation stability in demanding applications.
5. Consistent Quality For Global Industry: Supplied as high-purity colorless to light yellow liquid with consistent assay and quality, dodecylbenzene gives detergent, electrical, thermal and lubricant manufacturers a dependable alkylbenzene with flexible packaging and stable supply.
