  • Cumene Hydroperoxide C9h12o2 Pubchem

    Cumene hydroperoxide is obtained by oxidizing cumene with air, usually in a cascade of stirred-tank reactors or bubble columns at temperatures in the range of 100-140 c and a pressure of 6-7 bar and usually with small amounts of a buffer to prevent acids from building up.Since cumene hydroperoxide, as a tertiary alkyl hydroperoxide, is much.

  • 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 catalyst 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.

  • Design And Simulation Of Cumene Plant Using

    Cumene production process is gaining importance and so the process needs to be studied and better ideas suggested such that the production cost is reduced.With the advent of computers and simulating software like aspen plus it is possible to design and optimize a particular process.

  • Phenol Production And Manufacturing Process Icis

    Phenol was first isolated from coal tar in the coking of coal, but the first commercial process was the sulphonation of benzene and subsequent fusion with caustic soda.There are now three synthetic routes to phenol with cumene-based technology being the dominant process.Here, benzene and propylene are reacted to form cumene, which is oxidised to the hydroperoxide, followed by acid.

  • What Is The Equation For The Preparation Of Phenol

    Cumene is nothing but isopropyl benzene.It is air oxidised in presence of cobalt naphthenate in naco to form cumene hydroperoxide,which is decomposed by dilute acid to give phenol alongwith acetone.

  • Cumene Process Technology Applications Patent
