  2. Olefin conversion technology - Wikipedia

    en.wikipedia.org/wiki/Olefin_conversion_technology

    Olefin Conversion Technology, also called the Phillips Triolefin Process, is the industrial process that interconverts propylene with ethylene and 2-butenes. [1] The process is also called the ethylene to propylene (ETP) process. In ETP, ethylene is dimerized to 1-butene, which is isomerized to 2-butenes.

  3. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    Olefin metathesis has several industrial applications. Almost all commercial applications employ heterogeneous catalysts using catalysts developed well before the Nobel-Prize winning work on homogeneous complexes. [6] Representative processes include: [1] The Phillips Triolefin and the Olefin conversion technology. This process interconverts ...

  4. Propylene - Wikipedia

    In the Phillips triolefin or olefin conversion technology, propylene is interconverted with ethylene and 2-butenes. Rhenium and molybdenum catalysts are used: [10]

  5. Shell higher olefin process - Wikipedia

    en.wikipedia.org/wiki/Shell_higher_olefin_process

    The Shell higher olefin process (SHOP) is a chemical process for the production of linear alpha olefins via ethylene oligomerization and olefin metathesis invented and exploited by Shell plc. [1] The olefin products are converted to fatty aldehydes and then to fatty alcohols , which are precursors to plasticizers and detergents .

    This carbene collapses with loss of carbon dioxide to give the olefin. Proposed Mechanism of the Corey-Winter Olefination An alternative mechanism does not involve a free carbene intermediate, but rather involves attack of the carbanion by a second molecule of trimethylphosphite with concomitant cleavage of the sulfur-carbon bond.

  7. Kharasch–Sosnovsky reaction - Wikipedia

    en.wikipedia.org/wiki/Kharasch–Sosnovsky_reaction

    The Kharasch–Sosnovsky reaction is a method that involves using a copper or cobalt salt as a catalyst to oxidize olefins at the allylic position, subsequently condensing a peroxy ester (e.g. tert-Butyl peroxybenzoate) or a peroxide resulting in the formation of allylic benzoates or alcohols via radical oxidation. [1]
