Special features of the action of inhibitors in liquid-phase oxidation of hydrocarbons

Znamenskaya, O.A. / Viliyanskaya, G.D. / Kulikovskaya, T.N. / Mutovkina, T.A.

Abstract 1. 1. The antioxidizing activity of substitutd phenol depends considerably on the degree of screening of the hydroxyl group and on the radical which is in the p-position to this group. 2. 2. The direction of catalytic action of β-naphthol and DP-11 is determined by the concentration used: in small amounts they accelerate, while in large amount, they slow down oxidation. 3. 3. Inversion of the oxidizing synergistic effect of a twin additive, consisting of DP-11 and a mixture of amines, to antioxidizing effect dependent on a change of concentration, is described as double synergism.
