ABSTRACT:
Disclosed is a process for the oxidation of 4,4'-diisopropylbiphenyl which gives an excellent ratio of dihydroperoxide to monohydroperoxide and a low amount of other oxygenated compounds. The dihydroperoxide can be converted, by known procedures, to 4,4'-biphenyldiol or a diester thereof which are valuable monomers used in the manufacture of high performance polyesters. Certain of the disclosed compounds such as the dihydroperoxide, monohydroperoxides and diesters are new compositions of matter.
