Definition

Noun: 1. An unsaturated hydrocarbon: "butene" refers to any of three gaseous, isomeric hydrocarbons with the formula C₄H₈. It is an alkene, meaning it contains a carbon-carbon double bond, and is used primarily as a chemical feedstock in industrial processes, especially for making synthetic rubbers and plastics.

Examples of Usage

• As a chemical compound:
  • The plant separates butene from the other components of the gas stream.
  • Polybutene is a polymer derived from the polymerization of butene.
  • The chemical properties of butene make it a valuable monomer.

Advanced Usage

• In chemical nomenclature: The three isomers are specifically named: 1-butene, cis-2-butene, and trans-2-butene. The number indicates the position of the double bond in the carbon chain.
  • The reactivity differs slightly between 1-butene and 2-butene.

Variants and Related Words

• Butylene (n): A synonym for butene, often used in industrial contexts.
  • Butylene is a key feedstock for the petrochemical industry.
• Isobutylene (n): An isomer of butene with a different structural formula (2-methylpropene).
  • Isobutylene is used to make butyl rubber for inner tubes.

Synonyms

• Butylene: An equivalent term for this hydrocarbon.
