摘要：
The oxidation of C-13-labeled ethyl linoleate (C-13-EL), a model compound for alkyd resins, was investigated by C-13 NMR in the presence of Co(II)-2-ethylhexanoate (Co-EH), Mn(acac)(3) (acac = acetylacetonate), and Mn(acaC)(3) in combination with 2,2'-bipyridine (bpy), respectively. The use of (CEL)-C-13 allows us, in an unprecedented way, to reveal the individual evolution of hydroperoxides (ROOH) and peroxy (ROOR) links by C-13 NMR and to quantify the oxidation intermediates during the oxidation. Mn(acac)(3) appeared to be less effective in decomposing ROOH than Co-EH and the Mn(acaC)(3)/bpy combination. Quantitative analyses were attempted for a few major C-13 peaks. (c) 2005 Elsevier Ltd.
