Typical Physical Characteristics

Normal alpha olefins, from C4 to C30+ carbon lengths, are high-quality intermediates. They are straight-chain hydrocarbons with a double bond in the terminal position. At ambient conditions, C4 is a gaseous product and C6 through C18 are clear water-white liquids with a distinctive olefinic odor. The C20+ products are solid at room temperature and have a white waxy appearance.
