Abstract
Official abstract text for this publication.
In a process for producing cyclohexylbenzene, hydrogen, and benzene are contacted in a first reaction zone under conditions effective to produce a product effluent containing residual benzene in the vapor phase and cyclohexylbenzene in the liquid phase. The product effluent is separated into a first stream that is rich in residual benzene in the vapor phase as compared to the product effluent and a second stream that is rich in cyclohexylbenzene in the liquid phase as compared to the product effluent. At least a portion of the first stream is cooled to condense at least a portion of the residual benzene in the vapor phase to the liquid phase and produce a condensate stream. At least a portion of the condensate stream is recycled to the first reaction zone.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for producing cyclohexylbenzene comprising: (a) contacting hydrogen and benzene in a first reaction zone under conditions effective to produce a product effluent comprising cyclohexylbenzene and residual benzene, wherein at least a portion of the residual benzene is in the vapor phase and at least a portion of the cyclohexylbenzene is in the liquid phase; (b) separating the product effluent into (i) a first stream that is rich in residual b…
