Abstract
Abstract The two-phase oxidations of 3,6-dimethoxydurene and xylenes in cyclohexane solutions with the aqueous solution of cerium ammonium nitrate were carried out in the presence of cationic, nonionic, and anionic surfactants. Both cationic (ammonium salt) and nonionic (Dipodand) surfactants inhibited the reaction. The anionic surfactant (sodium dodecyl sulfate, SDS) catalyzed these oxidations. From the product distribution it was concluded that the catalytic action of SDS is due to the binding of aromatic compounds and the Ce(IV) ions to the surface of the SDS micelles. The micellar oxidant has the high oxidation potential which should allow to oxidize the comparatively nonreactive substrates.
