General description

Cyclohexene is a cyclic alkene. Kinetics of its reaction with hydrogen in gas and liquid phases over different palladium catalysts supported on silica gel and alumina (temperature range = 264 to 308K and hydrogen pressures = 4 to 89kPa) was investigated. Cyclohexene is formed during the batch-wise partial hydrogenation of benzene over ruthenium catalysts in the presence of an aqueous zinc sulphate solution. Cyclohexene undergoes enantioselective catalytic oxidation in the presence of hydrogen peroxide over environment-friendly peroxytungstate-organic complex catalysts to afford adipic acid. Selective hydrogenation of benzene has been reported to afford cyclohexene. It is an important precursor for the preparation of various chemicals such as cyclohexanol, cyclohexene hydroperoxide, etc.

Application

Cyclohexene has been used to investigate the kinetics of its liquid-phase hydrogenation reaction in the presence of Pd-Al catalyst supported on biomorphic carbon. It may be used for the industrial preparation of cyclohexanol.
