摘要: The present invention relates to an improved method for producing phenol and acetone by oxidizing cumene into technical cumol hydroperoxide (CHP) through catalytic cleavage of the CHP. According to the invention, the oxidation products are concentrated to up to a cumene content ranging from 21 to 30 wt % in the technical cumol hydroperoxide, said mixture being used for the catalytic cleavage.
