the cumene process for phenol–acetone (pa) manufacture is one of the unique high-volume petrochemical processes in which simultaneously two products (phenol and acetone) are obtained from one reactant (cumene), each of the products finding useful application; however, which is most important, their reaction with one another in the joint synthesis …

Around 98% of cumene is used to produce phenol and its co-product acetone. However, the requirement of cumene is largely dependent on the use of phenol's derivatives which have resulted in increasing requirement rates for cumene. The largest phenol derivative is bisphenol-A (BPA) which supplies the polycarbonate (PC) sector.
