Cumene hydroperoxide is then hydrolysed in an acidic medium (the Hock rearrangement) to give phenol and acetone. In the process, pure benzene at 100.0 kmol/h is mixed with part of a benzene recycle stream, which is subsequently pressurized. Most of the worldwide production of phenol and acetone is now based on this method. [13][1], Mitsui Co. developed additional step(s) to hydrogenating ...
