vinylbenzene
Low (specialist/technical term)Technical/Scientific
Definition
Meaning
The chemical compound C₆H₅CH=CH₂, which is the monomer used to produce polystyrene.
Commonly known as styrene, it is a colorless oily liquid hydrocarbon used extensively in the production of plastics, resins, and synthetic rubber.
Linguistics
Semantic Notes
Primarily used in chemistry, polymer science, and industrial manufacturing contexts. The term 'styrene' is far more common in general technical use.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. 'Styrene' is the predominant term in both varieties.
Connotations
Neutral technical term. 'Vinylbenzene' explicitly describes the chemical structure (a benzene ring with a vinyl group).
Frequency
Extremely low frequency compared to 'styrene'. Used almost exclusively in formal chemical nomenclature or educational contexts to emphasize structure.

By CEFR Level
- N/A
- Vinylbenzene is another name for a chemical called styrene.
- It is used to make plastic.
- The industrial production of vinylbenzene typically involves the dehydrogenation of ethylbenzene.
- As a monomer, vinylbenzene's double bond allows for chain-growth polymerization.
- While 'styrene' is the prevalent industrial term, IUPAC nomenclature prescribes 'vinylbenzene' or 'ethenylbenzene' for the compound C₆H₅CH=CH₂.
- The reactivity of the vinyl group in vinylbenzene makes it susceptible to radical-initiated polymerization processes.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation 'винилбензол' is correct but less common than 'стирол' (styrene).
- Risk of confusing with 'винил' (vinyl, PVC) which is a different polymer.
Common Mistakes
- Misspelling as 'vinylbenzen' or 'vinlybenzene'.
- Using it in non-technical contexts where 'styrene' is expected.
- Incorrectly capitalizing it as a proper noun.

FAQ
Frequently Asked Questions
Yes, vinylbenzene (styrene) is flammable, volatile, and exposure can have health effects. It requires careful handling.
To explicitly highlight its chemical structure as a derivative of benzene with a vinyl substituent, often in an educational or precise nomenclature context.
It is the primary monomer used in the manufacture of polystyrene plastic and copolymers like ABS (Acrylonitrile Butadiene Styrene).
No, it would sound highly technical and odd. Use 'styrene' if necessary, but it's not a common everyday word.
