Abstract:

Radiolytic degradation echanisms of diphenyl ether were studied. These mechanisms involve polymerization reactions and scission reactions of the C-O bond of the ether with formation of phenyl and phenoxy-free radicals. The reactions of these free radicals with diphenyl ether explain most of the chemical changes observed. The reaction of the phenyl radical at the ortho position of diphenyl ether results in the formation of phenol however, a small amount of this radical forms benzene. The remainder of the phenyl radicals appear to react at the meta and para positions of the ether molecule to form biphenylyl phenyl ethers. The mode of the phenoxy radical reactions is less clear they appear to react with diphenyl ether to form isomeric diphenoxybenzenes.
