Sorry, no etymologies found.


  • There is, quite often, an excess of propene, especially in oil refineries that do not have petrochemicals, as in the United States.

  • The "gasoline" version (Figure 1) consists of dimerising propene to high-octane isohexenes.

    Yves Chauvin - Autobiography

  • Both of these mechanisms were based on smog chamber experiments involving butane and propylene or propene, if you're a nomenclature purist.

    Hot Buttered

  • So I suggested that they load one side of the chamber with a standard mix of NOx and propylene or propene, or methyl ethane, which are different words for the same stuff, and the other side with the same mix, plus some toluene.

    The Scientific Method

  • In the next step this rapidly reacts either with Nu - and gives the substitution product or transfers a proton to the solvent or Nu - to give propene.

  • The rates of Hf-Zn/Zn-Al transfer are much faster than direct Hf-Al exchange, and all the chain-transfer rates are faster than the propene insertion step, Sita notes.

  • During polymerization, propene monomer units insert between hafnium and the existing polypropylene chain, Sita explains.

  • The palladium catalysts outperformed the platinum ones in nitric oxide and propene conversion; however, they fell short in the processing of propane unless the temperature was above 320 ºC (600 ºF).

  • Gouw found that the concentrations of ethene and propene -- which both contribute to ozone formation -- dropped by 52 percent and 48 percent respectively between 2000 and 2006. - latest science and technology news stories

  • The team tested the filters 'ability to act as catalysts by depositing palladium onto the nanotubes and using them to turn propene into propane, a benchmark test for catalysis. - latest science and technology news stories
