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
[edit | edit source]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]
