Definition

Noun: A colorless, oily liquid hydrocarbon. It is the fundamental monomer unit used in the industrial production of the plastic polystyrene.

Usage

"Vinylbenzene" is a technical and chemical term. It is primarily used in scientific, industrial, and manufacturing contexts to refer to the specific chemical compound before it is polymerized. In common usage, especially in manufacturing and chemistry, it is more frequently called by its other name, styrene.

Examples

• The plant produces vinylbenzene for polymerization into various plastic products.
• Safety protocols are strict when handling vinylbenzene due to its volatile nature.
• Vinylbenzene is polymerized to form clear, rigid polystyrene plastic.

Advanced Usage

• Industrial Process: The term is used to specify the raw material feed in chemical engineering processes.
  • The reactor was charged with vinylbenzene and initiator.

Variants and Related Words

• Styrene: The most common synonym for vinylbenzene in all contexts.
• Phenylethylene: A less common systematic IUPAC name for the same compound.
• Polystyrene (n): The polymer formed by linking many vinylbenzene (styrene) monomer units together.
  • Expanded polystyrene is often used for insulation and packaging.

Synonyms

• Styrene: The direct and most widely used synonym.
• Phenylethylene: A formal chemical name.
