In the presence of H202, H202 + Fe^3+, NaOel, OH + 02 oxidants, 1,3-benzenediol (80)
enters into reaction of oxidative polycondensation and forms the oligomer product,
including dihydrooxyphenylene links. The kinetic regularities of 80 oxidative polycondensation
with oxygen in the alkaline medium have been studied by volumetric and EPR
methods. It has been established that the reaction follows a first order both in monomer
and alkali. In the reaction course the quintiplet EPR signals have been registered, each
line of which is faintly split into a triplet, that has been assigned to the dimeric radical. It
has been established that BO oligomer oxidation with oxygen in the alkaline medium proceeds
without an induction period and has a first order in relation to the concentration of
dihydroxy- oxyphenylene-linked anions. At the same time, the accumulation of relatively
stable macroaroxylic radicals has been observed. The mechanism of 1,3-BO oxidative
polycondensation has been suggested, lncludinq the stages of single-electron oxidation
of SO anion into oxyphenoxyl radicals and recombination of their resonance forms.
