ABSTRACT:
A portion of a recycle stream obtained from the reaction mixture resulting from the oxidation of an aryl tertiary alkane and containing primarily aralkyl tertiary monohydroperoxide, unreacted aryl tertiary alkane, a minor amount of aralkyl tertiary polyhydroperoxide and other by-products is separated to obtain a fraction containing substantially all of the polyhydroperoxide and at least some of the by-products, the fraction then being introduced into a rearrangement zone to convert at least a portion of the polyhydroperoxide to the corresponding polyphenol.
