Description

Application

1,3-Butadiene can be used:

• In the synthesis of 1,6-hexanedial (adipic aldehyde) by bis-hydroformylation using rhodium as a catalyst.
• As a monomer for the synthesis of cis-1,4-polybutadiene by polymerization using cobalt(II) and nickel(II) complex catalysts.
• As a precursor for the selective synthesis of butene by hydrogenation reaction.
