Initiated oxidation of dibutyl ether in the presence of inhibitors
- 23 Downloads
It was found that unlike ionol, amines effectively inhibit the oxidation of dibutyl ether. The stoichiometric inhibition coefficient for amines is close to two. During the initiated oxidation of dibutyl ether in the presence of inhibitors, an exchange takes place of cyanoisopropyl peroxy radicals for the peroxy radicals of dibutyl ether. The mechanism of the reaction with p-phenylenediamine (p-PDA) probably consists in the formation of a fairly stable complex consisting of an amine molecule and two peroxy radicals. This reaction does not result in the formation of a hydroperoxide.
