Propylene is a colorless, highly flammable gas with weak odor. It is the second simplest member of the alkene class of hydrocarbons and one of the major building blocks of the petrochemical industry. Upon hydrating conditions propylene forms isopropyl alcohol. Aldehydes and high alcohols can be prepared from propylene by oxosynthesis process. Free radical chlorination of propylene at 500°C results in allyl chloride. Being oxidized in the presence of CuSeO3 it forms acrolein; reaction with NO at 450-500°C results in acrylonitrile. Propylene can be polymerized on Ziegler-Natta catalyst into polypropylene.


Propylene is typically obtained via two main routes: either as a co-product of the refinery catalytic cracking process used to make gasoline or as a co-product of the steam cracking process used to make ethylene.


More than 60% of the world's production of propylene is used to make polypropylene. Also it is used:

  • in manufacture of lube oils, lubricants;
  • as an intermediate to prepare acrylonitrile (which is converted to acrylic fibres and coatings);
  • propylene tri- and tetramers are the components of detergents;
  • as a fuel gas for various industrial processes;
  • as a raw material to produce isopropyl alcohol, propylene oxide, glycerol, cumene and other chemical products;

    Propylene is a key component of countless end use products.
