Primary processes of stabilizer action in radiation-induced alkane oxidation

Abstract

Results of pulse-radiolytic model experiments on the auto-oxidation of long-chain n-alkanes and auto-oxidation retardation are presented. In pure n-heptadecane and solutions of di-t-butyl-p-cresol or diphenylamine the reaction of alkyl radicals with oxygen and the corresponding competition reactions with the stabilizer prototypes have been characterized by spectroscopic and kinetic data. A reaction mechanism describing the radiation-induced processes within the system long-chain n-alkane–oxygen–stabilizer is discussed.
