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.

Intramolecular reductive coupling of cycloalkanones tethered to alkynoates in the presence of (η(2)-propene)titanium was successfully performed to provide hydroxy-esters in a diastereoselective manner. Subsequent lactonization afforded angularly fused unsaturated tricyclic lactones which represent relevant substructures of numerous bioactive compounds.

The use of bis(1,3-di-tert-butylimidazolin-2-iminato) titanium dichloride (1) and dimethyl (2) complexes in the polymerization of propylene is presented. The complexes were activated using different amounts of methylalumoxane (MAO), giving in each case a very active catalytic mixture and producing polymers
