Products Description of Propylene
Propylene, with the structural formula CH₂=CHCH₃, is the second simplest member of the olefin family. It ranks among the most important organic chemical feedstocks, surpassed only by ethylene and benzene in industrial importance.
Industrial Production Sources
Propylene is typically recovered from gases generated during thermal cracking and catalytic cracking processes, and is also obtained as a byproduct of ethylene production via light oil cracking.
Chemical Reactivity
The unsaturated carbon–carbon double bond in propylene enables addition reactions with hydrogen, halogens, and hydrogen halides, as well as addition polymerization.
Major Downstream Applications
As a key raw material, propylene is used to produce acrylonitrile, polypropylene, ethylene–propylene rubber, propylene oxide, acetone, and other synthetic resins, along with synthetic rubber, synthetic fibers, and plastics.

Product Application of Propylene
Propylene is a fundamental raw material in the chemical industry and serves as a key feedstock for a wide range of downstream chemicals.
Through gas-phase oxidation, propylene is converted into acrolein, which is further used to produce acrylic acid, allyl alcohol, glyceraldehyde, hydroxyacetaldehyde, and the important food and feed additive methionine.
Ammonia oxidation of propylene yields acrylonitrile, a vital raw material for synthetic fibers, synthetic rubber, and plastics.
Chlorination of propylene produces chloropropylene, which can be further transformed into allyl alcohol, propylene dichlorohydrin, chloropropionitrile, and other intermediates used in glycerin, epoxy resins, chlorohydrin rubber, and surfactants.
Through alkylation, propylene is used to produce cumene, the primary intermediate for phenol production, with acetone generated as a valuable co-product.
Oxo synthesis of propylene produces n-butyraldehyde and isobutyraldehyde, which are important intermediates for manufacturing plasticizers, dyes, solvents, pesticides, and various other organic chemicals.
Hydration of propylene produces isopropyl alcohol, which is further used to manufacture acetone, isopropylamine, and isopropyl esters.
Propylene can also undergo dimerization, trimerization, polymerization, and tetramerization to yield products such as ethylene, propylene trimers, polypropylene, and dodecene, the latter serving as an important intermediate for surfactant production.
