Cumene → 2-Phenyl-2-propanol

Participants

Reaction Steps

In the manufacture of cumene hydroperoxide (CHP) wherein cumene is oxidized to CHP, the improvement comprising refining the cumene hydroperoxide product stream containing, in weight percents, about 80 to about 89 CHP, about 0.6 to about 1.6 water, about 0.5 to about 2.0 acetophenone, about 2 to about 15 cumene, and about 5 to about 9 dimethylbenzyl alcohol to obtain a product substantially reduced in color, water, acetophenone, and dimethylbenzyl alcohol, by subjecting said product stream to a first evaporation step at a temperature of 150° to 210° F. and pressure of 2 to 10 mm Hg, passing the residue therefrom to a second evaporation step at a temperature of about 135° to about 210° F. and a pressure of about 0.5 to about 8 mm Hg, and condensing the vapors therefrom to recover a refined cumene hydroperoxide.
