Mechanism of catalytic oxidation of water-lipid substrate

The processes of ethyl oleate water-emulsion oxidation in the presence of copper (II) complexes with α-alanine as a catalyst were investigated spectroscopically. UV spectra of the samples revealed the competitive nature of the formation and decomposition of hydroperoxides in the course of oxidation....

Description
Summary:The processes of ethyl oleate water-emulsion oxidation in the presence of copper (II) complexes with α-alanine as a catalyst were investigated spectroscopically. UV spectra of the samples revealed the competitive nature of the formation and decomposition of hydroperoxides in the course of oxidation. Vis spectra of the aqueous phase revealed the constant presence of copper (II) complex with α-alanine and the formation of a similar complex with copper (I) in organic phase. The involvement of these complexes in the reactions of chain nucleation and decay of hydroperoxides is suggested.
