Description

Dodecylbenzene CAS NO 25265-78-5 is a high-purity, linear alkylbenzene (LAB) compound that serves as a critical intermediate in the synthesis of surfactants and detergents. Its consistent quality and defined molecular structure are essential for ensuring predictable performance and high yields in downstream chemical manufacturing. This product is primarily required by industrial manufacturers in the production of biodegradable linear alkylbenzene sulfonate (LAS), a key ingredient in household and industrial cleaning formulations, as well as by specialty chemical producers for various synthesis applications.

Application

• Primary raw material for the sulfonation process to produce Linear Alkylbenzene Sulfonate (LAS), a major biodegradable surfactant used in liquid and powder detergents.
• Intermediate in the synthesis of other specialty surfactants and emulsifiers for industrial and institutional cleaning products.
• Key feedstock in the production of oil-soluble sulfonates, which are used as lubricant additives and in enhanced oil recovery.
• Chemical intermediate for manufacturing plasticizers and other polymer additives.
• Used in research and development laboratories for organic synthesis and process optimization studies.
• Component in the formulation of certain industrial degreasers and solvent blends.
