Benzene is converted to cyclohexylbenzene by acid-catalyzed alkylation with cyclohexene. [6] Cyclohexylbenzene is a precursor to both phenol and cyclohexanone. [7] Hydration of cyclohexene gives cyclohexanol, which can be dehydrogenated to give cyclohexanone, a precursor to caprolactam. [8] The oxidative cleavage of cyclohexene gives adipic acid.
Chemical Safety Reports are the main end point for data assessment under REACH (the European Community Regulation on chemicals and their safe use, concerning the Registration, Evaluation, Authorisation and Restriction of Chemical substances [4]) in which hazard and exposure data are considered together to assess the risk of a substance. [5]
Cyclohexylbenzene is now industrially produced by the acid-catalyzed alkylation of benzene with cyclohexene. [ 3 ] [ 4 ] The process can proceed using benzene as the exclusive organic precursor. Its partial hydrogenation gives cyclohexene, which alkylates the unhydrogenated benzene.
4-Methylcyclohexene is an organic compound consisting of cyclohexene with a methyl group substituent attached to carbon most distant from the alkene group. Two other structural isomers are known: 1-methylcyclohexene and 3-methylcyclohexene. All are colorless volatile liquids classified as a cyclic olefins. They are specialized reagents.
In recent times the catalytic oxidation of cyclohexene by (immobilized) metalloporphyrin complexes has been found to be an efficient way. [7] [8] In laboratory, cyclohexene oxide can also be prepared by reacting cyclohexene with magnesium monoperoxyphthalate (MMPP) in a mixture of isopropanol and water as solvent at room temperature. [9]
4-Vinylcyclohexene is an organic compound consisting of a vinyl group attached to the 4-position of the cyclohexene ring. It is a colorless liquid. Although chiral, it is used mainly as the racemate. It is a precursor to vinylcyclohexene dioxide. [4]
1-Methylcyclohexene an organic compound consisting of cyclohexene with a methyl group substituent attached to the alkene group. Two other structural isomers are known: 3-methylcyclohexene and 4-methylcyclohexene. All are colorless volatile liquids. They are specialized reagents.
