Application
trans-2-Butene can be used as a monomer unit to produce high molecular weight polyolefins with well-defined microstructures by nickle-catalyzed polymerization reaction. It is also used as a reactant in the isomerization reaction to produce the corresponding isomer using acid-activated catalysts.
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.
