General description

Propylene is a nonpolar olefin. It is commonly used as a precursor for the synthesis of cumene, propylene oxide,acrylonitrile, and isopropanol. Selective oxidation of propylene in a gas containing oxygen and hydrogen over Au/TiO2 catalysts has been reported. Polymerization of propylene using Ziegler-Natta catalyst has been studied. Metal-catalyzed copolymerizations of nonpolar olefins (ethylene and propylene) with alkyl acrylates has been described. Copolymerization of propylene with the linear α-olefins 1-octene, 1-decene, 1-tetradecene, and 1-octadecene has been studied.

Application

Propylene may be used in the synthesis of propylene oxide via epoxidation with hydrogen peroxide, in the presence of titanium silicalite catalyst.

Packaging

Supplied in a Sure/Pac cylinder and has a brass needle valve with a male 1/4" NPTF outlet thread installed. Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.
