Useful:

Chemical Classes:UVCB
Canonical SMILES:CC=CC
Isomeric SMILES:C/C=C/C
Inhalation Risk:On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.
Effects of Short Term Exposure:Rapid evaporation of the liquid may cause frostbite. Exposure to high concentrations could cause asphyxiation. This may result in unconsciousness, respiratory arrest and death.
Uses 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.
