Cumene with o2

WebVerified by Toppr. 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. Acetone is separated by distillation. WebNov 9, 2016 · Cumene processes consist of two fundamental chemical reactions: cumene is oxidized with air to form cumene hydroperoxide, and cumene hydroperoxide is cleaved to yield phenol and acetone. In this process, approximately 0.46 kg of acetone and 0.75 kg of phenol are produced per kg of cumene feedstock. The
