Cyclohexylbenzene synthesis

13synthesis methods
Cyclohexylbenzene is produced by the acid-catalyzed alkylation of benzene with cyclohexene. Under vigorous stirring, the freshly distilled cyclohexene was added dropwise to the mixture of benzene and sulfuric acid, the temperature was kept at 15±5°C, and the addition was completed for about 0.5-1 h. After the addition, the reaction was continued for 1 h. The sulfuric acid layer is separated, the oil layer is washed with water, lye and water in turn, fractionated, firstly, the unreacted benzene is distilled off, then the 230-260 ℃ fraction is collected, and the positive boiling point fraction is collected by fractionation again to obtain the product cyclohexylbenzene.
