It is obtained as a byproduct of ethylene production from crude oil, combustion of biomass, waste incineration and exhaust gases. Piperylene is used as a monomer in the manufacture of plastics, adhesives and resins.[2] At standard conditions, piperylene is a colorless liquid.[3] Upon release into the aquatic environment it is expected to adsorb to suspended particulate matter (SPM) based on its estimated KOC value. The alternating double and single carbon-carbon bonds form a conjugated system. See also
