Engineers Guide_ Cumene Peroxidation Process for Phenol,

The cumene peroxidation process for the manufacture of phenol involves the liquid phase air oxidation of cumene to cumene peroxide, which in turn is decomposed to phenolAcetone Production and Manufacturing Process - ICIS,The cumene route, in which the acetone is coproduced with phenol, is the preferred technology because of its lower costs and nearly 90% of acetone is produced this way. The main process for manufacturing cumene involves the reaction of propylene and benzene in the presence of phosphoric acid-based catalysts or, more recently, zeolite catalysts.Industrial catalytic processes—phenol production,,Recently, renewed interest in alternative routes to phenol production has occurred due to the potential burden of producing by-products such as acetone. Unlike the cumene peroxidation route, direct oxidation of benzene with nitrous oxide or hydrogen peroxide or oxidation of toluene in a two-step process does not produce co-products such as acetone.Production of phenol from cumene - ScienceDirect,This reaction gave optimum results when carried out in a film reactor.

The hydroperoxide is mixed with dilute sulphuric acid at 60 - 70ºC, to produce both phenol and propanone (acetone) as products. The decomposition of cumene hydroperoxide to phenol and acetone is often described as a cleavage reaction.Production of Phenol | Chemical Reactor | Chemical Reactions,Cumene peroxidation process is a process involves the liquid phase air oxidation of cumene to cumene peroxide, which in turn is decomposed to phenol and acetone by the action of acid.During the cumene peroxidation process, there are two main raw materials used in this process which are cumene and oxygen. Oxygen is a gas form fluid.THE PRODUCTION OF CUMENE USING Zeolite CATALYST,About This Process Essentially all cumene produced worldwide is used as a feedstock in phenol plants, which convert it to phenol and acetone by cumene peroxidation. Therefore, the cumene and phenol markets are strongly tied. From 1993 to 1998, world cumene demand grew at a rate of 4.7%/yr, increasing from 5.6 million to 7.1 million t/yr.The Cumene Process for Phenol,PETROLEUM CHEMISTRY Vol. 47 No. 4 2007 THE CUMENE PROCESS FOR PHENOL–ACETONE PRODUCTION 275 captans, thiophene, etc.) and are formed during its oxi-cumene peroxidation process phenol production - valinaz,A Study On Cumene Plant Engineering Essay.
