Pemakaian (PubChem)
- Used as a chemical intermediate, e.g., polypropylene and isopropanol; [Merck Index]
- In polymerized form as polypropylene for plastics and carpet fibers. Chemical intermediate in the manufacture of acetone, isopropylbenzene, isopropanol, isopropyl halides, propylene oxide, acrylonitrile, cumene.
- Almost two thirds of the propene produced is used to produce polypropylene, a plastic material accounting for 25% of all plastic products today. Other important applications are propylene oxide, acrylic acid, acrylonitrile and cumene.
- Refinery-grade propene (i.e., 50-70% pure propene in propane) is obtained from refinery processes. The main uses of refinery propene are in liquefied petroleum gas for thermal use or as an octane-enhancing component in motor gasoline. Refinery-grade propene can also be used in some chemical syntheses.
- Chemical-grade propene is used extensively for most chemical derivatives (e.g., oxo alcohols, acrylonitrile, or polypropylene).
