Procedure

Referring to FIG. 1, this is a flow diagram of the hydroalkylation and dealkylation stages of an integrated process according to one example of the invention for converting benzene to phenol. In the process shown in FIG. 1, fresh benzene (line 11) and hydrogen (line 12) are introduced to a hydroalkylation reactor 13, where the benzene undergoes hydroalkylation to produce cyclohexylbenzene (CHB) and poly-cyclohexylbenzenes (PCHB). The effluent from the reactor 13, containing unreacted benzene in addition to the CHB and PCHB, is removed via line 14 and fed to a distillation system 15, which divides the effluent into a C6 fraction, a C12 fraction and a C18 fraction.
