propenonitrile
Definition
Noun: 1. A colorless, volatile, and flammable liquid chemical compound: Propenonitrile is an organic compound with the formula CH₂=CHCN. It is an unsaturated nitrile, meaning it contains both a carbon-carbon double bond (alkene group) and a nitrile group (-C≡N). It is primarily used as a monomer in the production of synthetic polymers and fibers.
Usage Examples
- The industrial synthesis of propenonitrile is a major chemical process.
- Propenonitrile must be handled with extreme care due to its toxicity and flammability.
- Acrylic fibers are often manufactured from polymers derived from propenonitrile.
Advanced Usage
- In polymer chemistry, propenonitrile is the monomer for polyacrylonitrile (PAN), a precursor for carbon fibers and many acrylic textiles.
- The compound is also known by its common name, acrylonitrile, which is used more frequently in industrial and commercial contexts.
Variants and Related Words
- Acrylonitrile (n): The common industrial name for propenonitrile.
- Polyacrylonitrile (PAN) (n): The polymer formed by the polymerization of propenonitrile/acrylonitrile monomers.
Synonyms
- Acrylonitrile
- Vinyl cyanide (a systematic name based on its structure)
- Cyanoethene
Notes on Meaning
The term propenonitrile is the systematic IUPAC name derived from its structure (propene + nitrile). Its primary and essentially only meaning is as the specific chemical compound described. In nearly all technical, industrial, and safety contexts, the synonym acrylonitrile is used interchangeably.
Noun
-
a colorless liquid unsaturated nitrile made from propene
