CONTINUOUS PREPARATION OF CYCLOHEXENE BY PARTIAL HYDROGENATION OF BENZENE

摘要

Continuous preparation of cyclohexene by partial hydrogenation of benzene Cyclohexene is prepared by partial hydrogenation of benzene with hydrogen in the presence of water and a ruthenium catalyst at elevated temperatures and superatmospheric pressure by A continuous process in which benzene is introduced in gaseous form and the resulting cyclohexene is discharged in gaseous form and the catalyst is present in solution or suspension in a liquid, aqueous phase.
