CONCURRENT IODIMETRIC DETERMINATION OF CUMENE HYDROPEROXIDE AND DICUMENYL PEROXIDE USED FOR REACTION CONTROL IN DICUMENYL PEROXIDE SYNTHESIS

A method for the iodimetric determination of cumene hydroperoxide (HPC ) and dicumenyl peroxide (DC) has been established. This method makes possible the concurrent determination of these peroxides in mixtures c ontaining also 2-phenylpropan-2-ol, acetophenone and cumene. While ela borating this method, advantage was taken of the difference in the rea ctivity of hydroperoxides and peroxides in their reaction with iodide ions, depending on the reaction temperature. The effect of the presenc e of DC on the results for HPC determinations was ascertained using st atistical tests. The method can be used to analyse mixtures of other p eroxides and hydroperoxides, provided that they are soluble in acetic acid.
