Process for the preparation of an alkyl benzene

摘要

The invention relates to a process for the preparation of an alkyl benzene by catalytic dehydrogenation of the corresponding alkenyl cyclohexene in the gas phase in the presence of a diluent. A characteristic feature is that at least a part of the alkyl cyclohexane in the reaction product is used as diluent. Hydrogen can be used as an additional diluent according to the invention.
