Cyclohexenone is an organic compound which is a versatile intermediate used in the synthesis of a variety of chemical products such as pharmaceuticals and fragrances. [2] It is colorless liquid, but commercial samples are often yellow.
For example, the conjugate addition of methylamine to cyclohexen-2-one gives the compound 3-(N-methylamino)-cyclohexanone. Conjugated carbonyls react with hydrogen cyanide to 1,4-keto-nitriles. See hydrocyanation of unsaturated carbonyls. In the Nagata reaction the cyanide source is diethylaluminum cyanide.
Methylcyclohexanones are a group of three isomers: 2-methylcyclohexanone, 3-methylcyclohexanone, and 4-methylcyclohexanone. [1] They can be viewed as derivative of cyclohexanone. They can be prepared by oxidation of methylcyclohexane as well as partial hydrogenation of the corresponding cresols. All are colorless liquids. The 2- and 3-isomers ...
Cyclohexylbenzene (or phenylhexamethylene, as it was initially called) is the organic compound with the structural formula C 6 H 5 −C 6 H 11. It is a derivative of benzene with a cyclohexyl substituent (C 6 H 11). It is a colorless liquid.
The archetypal Beckmann rearrangement [4] is the conversion of cyclohexanone to caprolactam via the oxime. Caprolactam is the feedstock in the production of Nylon 6. [5] The Beckmann solution consists of acetic acid, hydrochloric acid and acetic anhydride, and was widely used to catalyze the rearrangement.
Cyclohexylamine has a low acute toxicity with LD 50 (rat; p.o.) = 0.71 ml/kg [6] Like other amines, it is corrosive. Cyclohexylamine is listed as an extremely hazardous substance as defined by Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act .
Most methylcyclohexane is extracted from petroleum but it can be also produced by catalytic hydrogenation of toluene: CH 3 C 6 H 5 + 3 H 2 → CH 3 C 6 H 11. The hydrocarbon is a minor component of automobile fuel, with its share in US gasoline varying between 0.3 and 1.7% in early 1990s [10] and 0.1 to 1% in 2011. [11]
Cyclohexane is a cycloalkane with the molecular formula C 6 H 12. Cyclohexane is non-polar . Cyclohexane is a colourless, flammable liquid with a distinctive detergent -like odor, reminiscent of cleaning products (in which it is sometimes used).
