Oct 11, 1998 · Acetone is often produced as a byproduct in the production of phenol. The cumene hydroperoxide generated in that process is cleaved to form phenol and acetone. Catalytic dehydrogenation of isopropanol can be chosen as an alternative synthetic rout e when highpurity acetone is required, such as in biomedical appliions.

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

Apr 23, 2010 · Acetone Production and Manufacturing Process. Early processes for the manufacture of acetone were based on the thermal decomposition of calcium acetate or the carbohydrate fermentation of starch or molasses. The ready availability of propylene in the 1960s led to routes based on the dehydrogenation of isopropyl alcohol or cumene peroxidation.

Around 98% of cumene is used to produce phenol and its coproduct 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 bisphenolA (BPA) which supplies the polycarbonate (PC) sector. PC resins are consumed in automotive appliions in place of ...

How is phenol manufactured by Cumene process?

Cumene is isopropyl benzene. Cumene in presence of sodium carbonate is oxidised by passing air or oxygen. The alyst is cobalt naphthenate. Temperature is 423 K. The product cumene hydroperoxide is heated with dilute sulphuric acid. It decomposes to phenol and by product acetone. Acetone is separated by distillation.
