Ethylbenzene
Ethylbenzene (CAS: 100-41-4, Formula: C6H5C2H5, Molar Mass: 106.17 g/mol) is a clear, colourless liquid with a distinct aromatic odour. This aromatic hydrocarbon is primarily used as a chemical intermediate in the production of styrene, which is a key component in the manufacturing of various plastics and synthetic rubbers. Its solvent properties also lend it to applications in paints, lacquers, and insecticides.
Styrene Production
Ethylbenzene is the principal precursor for styrene monomer production via dehydrogenation. Styrene is a vital building block for polymers like polystyrene, ABS, and SBR rubber.
Solvent Applications
Due to its solvency characteristics, ethylbenzene finds use in the formulation of paints, lacquers, varnishes, and as a solvent in the rubber industry. It is also utilised in pesticide and insecticide formulations.
Fuel Additive
Ethylbenzene can be used as an additive in gasoline to increase its octane rating, thereby improving fuel performance and efficiency.
