Description

(2-Decyl)Benzene CAS NO 4537-13-7 is a high-purity, branched-chain alkylbenzene derivative characterized by its specific decyl substitution pattern. This compound serves as a valuable intermediate and functional fluid component in advanced chemical synthesis and industrial formulations. It is primarily utilized by manufacturers in the lubricant, surfactant, and specialty chemical industries seeking tailored hydrocarbon performance.

Application

• Synthetic Lubricant Base Stock: Used as a high-performance hydrocarbon fluid in the formulation of synthetic engine oils, compressor oils, and industrial lubricants, offering excellent thermal and oxidative stability.
• Surfactant & Detergent Intermediate: Acts as a key hydrophobic precursor in the production of alkylbenzene sulfonates and other specialty surfactants for industrial and institutional cleaning products.
• Plasticizer & Polymer Additive: Employed as a processing aid and compatibilizer in polymer systems, including PVC and various elastomers, to enhance flexibility and processing characteristics.
• Organic Synthesis Building Block: Serves as a versatile intermediate in fine chemical and pharmaceutical synthesis, particularly for introducing lipophilic (decyl) groups into target molecules.
• Heat Transfer Fluid Component: Incorporated into formulations for non-aqueous heat transfer fluids due to its favorable boiling point and chemical inertness.
• Specialty Solvent: Used as a solvent or co-solvent in applications requiring a non-polar, high-boiling hydrocarbon medium, such as in coatings, adhesives, and agrochemical formulations.
