Sum Formula: C8H10
Molar Mass: 106.17 g/mol
Appearance: colorless liquid with an aromatic odor
Ethylbenzene is an aromatic hydrocarbon consisting of a benzene ring substituted with an ethyl group. It is primarily used as a chemical intermediate in the production of styrene and is also used in selected technical applications as a solvent and component of industrial formulations.
Due to its aromatic structure, volatility and solvent properties, ethylbenzene is used in chemical synthesis, coatings, paints, lacquers, varnishes and fuel-related technical applications.

Type of Compound: aromatic hydrocarbon, alkylbenzene
Applications:
Chemical Industry:
Used as a precursor in the synthesis of styrene, which is further polymerized to produce polystyrene plastics and resins.
Solvent Applications:
Used in paints, lacquers, varnishes and selected coating systems due to its ability to dissolve organic substances.
Fuel and Technical Applications:
May occur as a component in fuels and technical hydrocarbon mixtures.
Organic Synthesis:
Used as a starting material, solvent or model aromatic hydrocarbon in laboratory and industrial chemical work.
Key Properties:
Aromatic Structure: contains a benzene ring substituted with an ethyl group.
Solvent Properties: suitable for dissolving a range of organic materials.
High Flammability: vapors can form flammable mixtures with air.
Technical Intermediate: important precursor for styrene and related industrial chemistry.
