description 1. Field of the Invention A process for the cleavage of alkylaryl hydroperoxides includes steps for producing a mixture of a concentrate that contains at least one alkylaryl hydroperoxide to be cleaved and a cleavage product obtained from the cleavage of an alkylaryl hydroperoxide, dividing this mixture into at least two parts and cleaving the alkylaryl hydroperoxides in parallel at different temperatures. One of the two parts is treated at a temperature sufficiently high for an integrated thermal post-treatment to be achieved. The process consumes less energy since less steam has to be used. Problems which can result from fouling in heat exchangers are largely prevented. No second feed point for alkylaryl hydroperoxide has to be provided. The process can be used in the preparation of phenol and acetone by the Hock method.
