  • Applications

    Benzene, 1-ethyl-3,5-bis(1-methylethyl)- (CAS 15181-13-2), also known as 1-ethyl-3,5-diisopropylbenzene, is a high-boiling aromatic alkylbenzene used/considered as a nonpolar solvent and carrier in systems that demand thermal stability and low volatility, such as heat-transfer media, dielectric fluids, and base oils/diluents for lubricant additives, owing to strong solvency for waxes, resins and certain elastomers and a high flash point; its bulky alkyl substitution makes it a low-odor diluent for high-performance coatings, inks, adhesives and sealants, and a carrier for actives in agrochemical and industrial-cleaner formulations; in synthesis it serves as a feedstock for controlled sulfonation, alkylation, halogenation or oxidation to access derivatives (e.g., alkylbenzene sulfonates for specialized surfactants, intermediates for oil additives, polymer modifiers), and it may be used to tune viscosity/volatility in refrigeration compressor oils and specialty hydraulic fluids; at analytical and R&D scale it can function as a reference or matrix solvent for materials characterization and compatibility testing, with ultimate use determined by purity, isomer distribution, safety assessments and sector-specific regulations.
