Abstract
The kinetics of consumption ofp-phenylenediamine (PDA) in di-n-butyl ether (BE) subjected to oxidation was measured by following the accumulation of the product of the transformation of PDA. The effective rate constant of the reaction of peroxide radicals derived from BE (RO2) with PDA was measured (k 7 = 2·104 L mol−1 s-1) by the inhibitor method, Evidence confirming the formation of a stable complex of RO2, with PDA were obtained. This leads to retardation of oxidation without the formation of hydroperoxides of BE (ROOH) in the acts of chain termination on PDA.
