Acid cleavage of cumene hydroperoxide to phenol, acetone and alpha-methylstyrene

Acid cleavage of cumene hydroperoxide to phenol, acetone and alpha-methylstyrene

Technical cumylhydroperoxide of a wide composition range is cleaved in circulating reactors of a shell and tube design at the same elevated pressure as dicumyl peroxide is cleaved in a plug flow reactor with a recirculation ratio of at least 26. The cleavage process is controlled using two calorimet...

Zusammenfassung:Technical cumylhydroperoxide of a wide composition range is cleaved in circulating reactors of a shell and tube design at the same elevated pressure as dicumyl peroxide is cleaved in a plug flow reactor with a recirculation ratio of at least 26. The cleavage process is controlled using two calorimeters and controlling the absolute DELTA T value which is the difference in the temperature drop between the two calorimeters.
