Abstract: The present invention relates to a process for the preparation of phenol/acetone mixture from cumene. The invention thus aims a process for the production of phenol/acetone mixture from cumene, via cumene hydroperoxide (CHP), which comprises the following steps: a. oxidation of cumene with a gas containing oxygen to produce CHP, b. concentration of the solution containing CHP obtained from step a. by evaporation, to at least 70 percent by weight; c. production of phenol/acetone mixture by acid cleavage of CHP solution obtained from step b., in which step b. is carried out in a multiple effect evaporation system comprising at least 2 effects.
