butylene
Definition
Noun 1. A type of hydrocarbon: Any of three isomeric, gaseous, unsaturated hydrocarbons with the formula C₄H₈. These compounds are primarily used as chemical intermediates in industrial processes, notably in the production of synthetic rubbers and plastics.
Examples of Usage
- Noun:
- The chemical plant produces butylene as a key feedstock for its rubber manufacturing unit.
- One isomer of butylene, isobutylene, is polymerized to make butyl rubber.
- The properties of the three butylene isomers differ slightly due to their structural arrangements.
Advanced Usage
- In Chemical Nomenclature: The term "butylene" is a common name. In more precise IUPAC nomenclature, the isomers are called but-1-ene, cis/trans-but-2-ene, and 2-methylpropene (isobutylene).
- Industrial Context: In industry, butylenes are often discussed as part of the C4 stream from petroleum refining or steam cracking. They are separated and used in alkylation, polymerization, and as fuel additives.
Variants and Related Words
- Isobutylene (noun): A specific, important isomer of butylene (2-methylpropene), which is the monomer for polyisobutylene and butyl rubber.
- Butene (noun): The systematic name often used interchangeably with "butylene" for the unbranched isomers.
- Polybutylene (noun): A polymer made by polymerizing butylene, used in piping and plastic packaging.
Synonyms
- Butene (n): The preferred IUPAC name for the unbranched forms (but-1-ene, but-2-ene).
- C4 olefin (n): A broader industrial term referring to any four-carbon olefin or alkene, which includes the butylenes.
Related Phrases / Compound Terms
- Butylene oxide (noun): A cyclic ether derived from butylene, used as a chemical intermediate.
- Butylene glycol (noun): A diol (a compound with two alcohol groups) derived from butylene, used in cosmetics and as a solvent.
Noun
-
any of three isomeric hydrocarbons C4H8; all used in making synthetic rubbers
