Exempel på hur man kan använda PROPENE i en mening

• In industry, butyric acid is produced by hydroformylation from propene and syngas, forming butyraldehyde, which is oxidised to the final product.
• Benzene and propene are compressed together to a pressure of 30 standard atmospheres at 250 °C in presence of a catalytic Lewis acid.
• for the production of ethylbenzene, the precursor to polystyrene, from benzene and ethylene and for the production of cumene from benzene and propene in cumene process:.
• The traditional route proceeds via the conversion of propene to propylene chlorohydrin according to the following simplified scheme:.
• MAPD is produced as a side product, often an undesirable one, by cracking propane to produce propene, an important feedstock in the chemical industry.
• It converts synthesis gas (syngas) to methanol, and then converts the methanol to ethylene and/or propene.
• Acrylic acid was once manufactured by the hydrolysis of acrylonitrile, a material derived from propene by ammoxidation, but this route was abandoned because it cogenerates ammonium side products, which must be disposed of.
• It is produced industrially from propene and mainly used as a biocide and a building block to other chemical compounds, such as the amino acid methionine.
• The most widely used route is similar to the cumene process in reaction mechanism and involves the dialkylation of benzene with propene to give 1,4-diisopropylbenzene.
• The name comes from mix of propene and argentum, which refers to the typical reaction of the terminal alkynes with silver salts.
• Molybdenum trioxide is also a component of the co-catalyst used in the industrial production of acrylonitrile by the oxidation of propene and ammonia.
• In the cymene-cresol process, toluene is alkylated with propene to give p-cymene, which can be oxidatively dealkylated in a manner similar to the cumene process.
• Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid, which is the central intermediate in phenylpropanoid biosynthesis.
• Since the 1950s, most 1-butanol is produced by the hydroformylation of propene (oxo process) to preferentially form the butyraldehyde n-butanal.
• It can also be prepared by the halogen-exchange reaction between allyl chloride and hydrobromic acid or by the allylic bromination of propene.
• Japanese chemical companies have commercialized the use of the compounds in hydration of propene, oxidation of methacrolein, hydration of isobutene and n-butene, and polymerization of THF.
• For example, the relative rates of epoxidation increase upon methyl substitution of the alkene (the methyl groups increase the electron density of the double bond by hyperconjugation): ethylene (1, no methyl groups), propene (24, one methyl group), cis-2-butene (500, two methyl groups), 2-methyl-2-butene (6500, three methyl groups), 2,3-dimethyl-2-butene (>6500, four methyl groups).
• Phenylpropenes broadly are compounds containing a phenyl ring bonded to propene, more specifically those with an allyl group bonded to a benzene ring, having the parent structure of allylbenzene.
• It is used to convert isobutane and low-molecular-weight alkenes (primarily a mixture of propene and butene) into alkylate, a high octane gasoline component.
