Generation of peracetic acid on aging of perborate solution in acetic acid: kinetics of oxidation of N-methylaniline and N,N-dimethylaniline

Perborate solution in glacial acetic acid generates peracetic acid on aging, and the peracetic acid oxidation of N-methylaniline and N,N-dimethylaniline is fast. But perborate dissolved in ethylene glycol does not show the aging effect and the oxidation is smooth. The oxidation of N-methylaniline exhibits Michaelis-Menten dependence on the famine] and is apparent zero order in the oxidizing agent but the rate increases linearly with the initial concentration of perborate ([perboratejo). On the other hand, the oxidation of N,N-dimethylaniline is first order in the amine and the oxidizing agent but the rate shows Michaelis-Menten dependence on [perboratejo. The mechanism of oxidation is discussed and the rate law derived.
