  2. Propylene - Wikipedia

    en.wikipedia.org/wiki/Propylene

    Propylene, also known as propene, is an unsaturated organic compound with the chemical formula CH 3 CH=CH 2. It has one double bond , and is the second simplest member of the alkene class of hydrocarbons .

  3. Autoxidation - Wikipedia

    en.wikipedia.org/wiki/Autoxidation

    are made from benzene and propylene. Many variations of this reaction have been developed, e.g. use of diisopropylbenzene as a substrate. the autoxidation of cyclohexane yields cyclohexanol and cyclohexanone. [20] p-xylene undergoes auoxidation to terephthalic acid.

  4. Photo-oxidation of polymers - Wikipedia

    en.wikipedia.org/wiki/Photo-oxidation_of_polymers

    Photo-oxidation is a form of photodegradation and begins with formation of free radicals on the polymer chain, which then react with oxygen in chain reactions. For many polymers the general autoxidation mechanism is a reasonable approximation of the underlying chemistry.

  5. Propylene glycol - Wikipedia

    en.wikipedia.org/wiki/Propylene_glycol

    Related to this application, propylene glycol reacts with propylene oxide to give oligomers and polymers that are used to produce polyurethanes. [7] Propylene glycol is used in water-based acrylic architectural paints to extend dry time which it accomplishes by preventing the surface from drying due to its slower evaporation rate compared to water.

  6. Cumene process - Wikipedia

    en.wikipedia.org/wiki/Cumene_process

    First stage of Hock process: alkylation of benzene with propylene. Second stage of Hock process: autoxidation of cumene. The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene.

  7. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    This process interconverts propylene with ethylene and 2-butenes. Rhenium and molybdenum catalysts are used. Nowadays, only the reverse reaction, i.e., the conversion of ethylene and 2-butene to propylene is industrially practiced, however. [6] Shell higher olefin process (SHOP) produces (alpha-olefins) for conversion to detergents. The process ...

  8. Propylene oxide - Wikipedia

    en.wikipedia.org/wiki/Propylene_oxide

    Propylene oxide is an acutely toxic and carcinogenic organic compound with the molecular formula C 3 H 6 O. This colourless volatile liquid with an odour similar to ether , is produced on a large scale industrially.

  9. Steam cracking - Wikipedia

    en.wikipedia.org/wiki/Steam_cracking

    The products produced in the reaction depend on the composition of the feed, the hydrocarbon-to-steam ratio, and on the cracking temperature and furnace residence time. Light hydrocarbon feeds such as ethane, LPGs, or light naphtha give mainly lighter alkenes, including ethylene, propylene, and butadiene.
