Conclusions
-
1.
ESR signals for the dehydroascorbic acid radical-anions (D−) resulting from the interaction of AA with aqua ions and mono- and bis-α,α′-dipiridyl (dipy) complexes of Cu2+ have been recorded in a streaming system.
-
2.
An expression for the rate of generation of D− has been obtained, the mechanism of destruction of radicals had been established, and rate constants for the reaction of D− with Cu2, Cu2+dipy2, and Cu+ have been determined.
-
3.
Study has been made of the affect of acetonitrile on formation and destruction of radicals.
