Concurrent iodimetric determination of cumene hydroperoxide and dicumenyl peroxide used for reaction control in dicumenyl peroxide synthesis

Abstract

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 containing also 2-phenylpropan-2-ol, acetophenone and cumene. While elaborating this method, advantage was taken of the difference in the reactivity of hydroperoxides and peroxides in their reaction with iodide ions, depending on the reaction temperature. The effect of the presence of DC on the results for HPC determinations was ascertained using statistical tests. The method can be used to analyse mixtures of other peroxides and hydroperoxides, provided that they are soluble in acetic acid.
