Exempel på hur man kan använda CYCLOHEXANONE i en mening

• Hydration of cyclohexene gives cyclohexanol, which can be dehydrogenated to give cyclohexanone, a precursor to caprolactam.
• This process coforms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid.
• Adipic acid is produced by oxidation of a mixture of cyclohexanone and cyclohexanol, which is called KA oil, an abbreviation of ketone-alcohol oil.
• It was estimated that 90% of all caprolactam is synthesised from cyclohexanone (1), which is first converted to its oxime (2).
• Robinson and Rapson found in 1935 that the interaction between cyclohexanone and α,β-unsaturated ketone afforded the desired cyclohexenone.
• A multicomponent reaction featuring a Knoevenagel condensation is demonstrated in this MORE synthesis with cyclohexanone, malononitrile and 3-amino-1,2,4-triazole:.
• Chemicals found in the cars included the carcinogen benzene, two other possible carcinogens cyclohexanone and styrene, and several other toxic chemicals.
• For example, oxidation of cyclohexane into cyclohexanol and cyclohexanone and ortho-xylene into phthalic anhydride have led to catastrophic explosions when reaction control failed.
• In the ring-expansion reaction of cyclohexanone with diazald, the bisulfite reaction is reported to allow differentiation between the primary reaction product cycloheptanone and the main contaminant cyclooctanone.
• An example of the scientific use of scandium triflate is the Mukaiyama aldol addition reaction between benzaldehyde and the silyl enol ether of cyclohexanone with an 81% yield.
• This reaction is an example of green chemistry, as it is more environmentally friendly than the traditional method of oxidizing cyclohexanol or cyclohexanone with nitric acid or potassium permanganate, which produce hazardous wastes.
• For example, the enolate from treating cyclohexanone with potassium hydride produces 2-allylcyclohexanone in 90% yield when triethylborane is present.
• This intermediate then fragments to the imine 4a and the saturated cyclohexanone 4b in a non-reversible reaction and both fragments recombine in a condensation reaction to the conjugated imine 5.
• Caprolactone is prepared industrially by Baeyer-Villiger oxidation of cyclohexanone with peracetic acid.
• HNO is generated via organic oxidation of cyclohexanone oxime with lead tetraacetate to form 1-nitrosocyclohexyl acetate:.
• Ethinamate (1-ethynylcyclohexanone carbamate) is synthesized by combining acetylene with cyclohexanone to make 1-ethynylcyclohexanol, and then transforming this into a carbamate by the subsequent reaction with phosgene, and later with ammonia.
• Reaction of cyclohexanone with ammonium carbonate and KCN under the conditions of the Bucherer-Bergs reaction led to hydantoin 1.
• Other large scale aldehydes and ketones are produced by autoxidation or hydrocarbons: benzaldehyde from toluene, acrolein from propylene, acetone from cumene, cyclohexanone from cyclohexanol.
• The cargo included approximately 5,000 barrels, other containers, and bags containing flammable substances (xylene, butanol, butyl acrylate, cyclohexanone, and sodium—contact of the sodium with water was the cause of the fire), toxins (aniline oil, diphenylmethane di-isocyanate, o-cresol, and dibutyl phthalate), and corrosives (phosphoric acid and phthalic anhydride).
• Cycloheptanone is also produced by the reaction of cyclohexanone with sodium ethoxide and nitromethane.
