In the method for producing at cyclohexyl benzene, in the first reaction zone, include residual benzene and include in liquid phase under the condition of product effluent of cyclohexyl benzene being effectively created in vapor phase, hydrogen is contacted with benzene. Product effluent is separated into compared with product effluent, in vapor phase, is rich in the first logistics of residual benzene, with compared with product effluent, in liquid phase, be rich in the second logistics of cyclohexyl benzene. With condensation at least a portion, the residual benzene in vapor phase becomes liquid phase and produces condensate stream in cooling at least a portion the first logistics. At least a portion condensate stream is recycled in the first reaction zone. |
