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.

Application of Fe-zeolites for urea-SCR of NO(x) in diesel engine is limited by catalyst deactivation with hydrocarbons (HCs). In this work, a series of Fe-zeolite catalysts (Fe-MOR, Fe-ZSM-5, and Fe-BEA) was prepared by ion exchange method, and their catalytic activity

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

A novel iron-catalysed tandem cross-dehydrogenative coupling and benzoannulation process was developed for the synthesis of biologically and synthetically important polysubstituted naphthalene derivatives from simple 1,2-aryl-propenes and styrenes in moderate to good yields.

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.
