Cis-2-butene
Cis-2-butene
Formula: C4H8
Cis-2-Butene (C4H8) is a colorless, flammable, liquefied gas with a slight aromatic odor. It is an acyclic alkene in the hydrocarbon family and is typically produced by the catalytic cracking of crude oil or through the dimerization of ethylene.
Applications include:
-
Gasoline blending to improve fuel performance.
-
Production of butadiene for synthetic rubber and polymer manufacturing.
-
Use as a chemical intermediate in specialty chemical synthesis.
-
Feedstock for alkylation processes in petrochemical refining.
-
Calibration or span gas in analytical applications.
