Application
cis-2-Butene is an unsaturated olefinic hydrocarbon used as a precursor in the polymerization of gasoline. It is also used to synthesize butadiene and other aliphatic C4/C5 organic molecules. It is also employed as a cross-linking agent.
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.
