Propylene

CAS RN: 115-07-1

Major Uses

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).
Polymer-grade propene contains minimal levels of impurities such as carbonyl sulfide that can poison catalysts used in polypropylene and propene oxide manufacture.
The chemical uses of propene in the order of their current industrial importance are polypropylene, propylene oxide, acrylonitrile, cumene, acrylic acid, and isopropanol.
