Dicumyl peroxide → Dicumyl peroxide

Participants

Reaction Steps

The reaction described in Example 2 was repeated with 14.7 gm (95 millimoles) cis-1,2-cyclohexanedicarboxylic anhydride substituted for the acetic anhydride. After a total reaction time of 125 minutes (at 18°±1° C.), 9.9% of the cumene hydroperoxide remained unreacted. The reaction was quenched (sodium acetate) after a total time of 245 minutes and, after recovery in a manner similar to Example 2, afforded 35.9 gm crude product which contained about 70% dicumyl peroxide. (An approximate value for dicumyl peroxide was obtained in this case because the elution of cis-1,2-cyclohexanedicarboxylic acid on the gas-liquid chromatography column partially overlapped with the dicumyl peroxide).
