6. 1. The Mechanism of the Reaction of the Peroxide Radicals of an Alcohol with Phenols and Aromatic Amines Phenols and aromatic amines decrease the rate of the oxidation of primary and secondary alcohols by terminating the chains in reactions with peroxide radicals, as in the oxidation of hydrocarbons [1]. The detailed mechanism of this reaction in alcohols, however, differs from that in hydrocarbons. In hydrocarbons. W (InH + RO~) = krnH [InH] [RO~], whereas in alcohols [79, 80] W (InH + RO~) = k7 [InH] [RO~] + k; [InH] [RO~]2.
At p~ = 760 mm Hg and 71°C, 86% of the chain termination takes place by the reaction> C(OH)OQ' + X. 2 X 103 liters /mole . 0 X 10 4• As in the case of aromatic amines, for quinone f = 23, that is, the quinone is regenerated by the reactions X+>C(OH)OO'-+XH+O~+>C=O, XH+ >C(OH)OO' -+X+ >C(OH)OOH. Thus quinone is a selective inhibitor, reacting selectively with the hydroxyperoxide radicals of the alcohol, and this has been made the basis of a new method for measuring the rate constants of the reactions of peroxide radicals with alcohols - the method of conjugated oxidation in the presence of a selective inhibitor [52].
The mechanism of inhibitor regeneration was studied in more detail for the case of a -naphthylamine in cyclohexanol [86]. The alcohol being oxidized contains three kinds of radical: hydroxyalkyl, hydroxyperoxide, and hydroperoxide. The ratio of these radicals depends on the concentration of ~,>CH(OH), and H2~ (Fig. 2), since they are formed and ..... 80 i:i ·0<:::: \ \ \ \ 60 ';; Fig. 2. 5 ferent initial HzOz concentrations; temperature 75°C. 6] 49 transformed according to the following reactions: >COH +02_ >C(OH)OO', >C(OH)OO'+HP2->C(OH)OOH+HO;, >C(OH)OOH :+±>C=0+H2 0 2 , HO~+ >CHOH _H 20 2 + >COH, Each of these radicals reacts with In' radicals in two directions: They reduce In' to InH, and they add on to In' (leading to the irreversible consumption of InH), For example, ks In' +HO~-InH+02' k~ In' +HO~_ InOOH-+ products.
