ABSTRACT:
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.
