Isopropyl benzene popularly known as Cumene is gaining a lot importance nowadays. Cumene is the major chemical used in the manufacturing of phenol and its co-product acetone on the industrial scale.
Cumene entered the market in 1944 by Hack and Lang when they proved cumene could be oxidized to form a hydrocarbon that decomposes to form phenol and acetone. The demand for cumene increased during World War II in order to help increase the octane rating of America's aviation fuel program.
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.
An improved process for the production of bisphenols is presented in which ketones and phenols are reacted in the presence of an acidic cationic exchange resin catalyst and a mercaptan cocatalyst. Prior to the reaction, alkyl alcohol is removed from the ketone stream. Cocatalyst is withdrawn from the reactor so that cocatalyst derivatives such as disulphide ions can be removed from the ...

Isopropyl benzene popularly known as Cumene is gaining a lot importance nowadays. Cumene is the major chemical used in the manufacturing of phenol and its co-product acetone on the industrial scale. It is also among the preliminary material in the production of acetophenone, methyl styrene, di-isopropyl benzene and di-cumyl peroxide.
- Collaborated with a team to design a cost-effective process for producing phenol and acetone from cumene using the program Aspen Plus V9 - Researched potential safety concerns associated with ...
Dec 02, 2008· Acetone is primarily used as a chemical intermediate in the manufacture of acetone cyanohydrin for methyl methacrylate, biphenol A, and adol chemicals. Direct solvent use accounts for about 30% of world demand for acetone. Acetone is almost exclusively produced via cumene peroxidation, as a coproduct of phenol.
•Experienced working with Aspen Hysys, Pipesysm and ASPEN Plus simulations. •Developed Heat and Material Balances (H&) for a satisfactory and low risk process with high production percentage (~95% of Acetone & Phenol). •Prepared equipment and instrument data sheets to have a better feasibility of each equipment specification.
