Piperylene

Hydrocarbon compound (CH3−CH=CH−CH=CH2)

Chemical compound

Piperylene or 1,3-pentadiene is an organic compound with the formula CH₃−CH=CH−CH=CH₂. It is a volatile, flammable hydrocarbon. It is one of the five positional isomers of pentadiene.

Reactions and occurrence

Piperylene is a typical diene. It forms a sulfolene upon treatment with sulfur dioxide.^[2]

Piperylene is the product of the decarboxylation of sorbic acid, a common anti-mold agent.^[3]

Piperylene is obtained as a byproduct of ethylene production from crude oil, combustion of biomass, waste incineration and exhaust gases. It is used as a monomer in the manufacturing of plastics, adhesives and resins.^[4]
