α-Tocoperol was reacted with an alkylperoxyl radical at 37℃ in ethanol or benzene, 2, 2'-azobis (2, 4-dimenthylvaleronitrile) (AMVN) being used to generate the peroxyl radical. The reaction products were 8a-(1-cyano-1, 3-dimethyl) butylperoxy-α-tocopherone and some other compounds. Methyl linoleate-peroxyl radicals were generated by the reaction of methyl linoleate with AMVN and reacted with α-tocopherol. The reaction products were four stereoisomers of methyl 13-(8a-peroxy- α-tocopherone)-9 (Z), 11 (E)-octadecadienoate and four stereoisomers of methyl 9-(8a-peroxy- α-tocopherone)-10 (E), 12 (Z)-octadecadienoate. From these reaction products of α-tocopherol, the reaction mechanism of α-tocopherol with peroxyl radicals was discussed.
