Synthesis and inhibitory activity of alkyl(hydroxyaryl)amines
O. I. Dyubchenko, V. V. Nikulina, E. I. Terakh, A. E. Prosenko, and I. A. Grigor´ev
The reaction of ω-(4-hydroxyaryl)haloalkanes with various nitrogencontaining agents afforded primary, secondary, and tertiary amino derivatives of 2,6-dialkylphenols. For the compounds synthesized, the reaction rate constants with peroxide radicals were measured for cumene and methyl oleate oxidation. The total inhibitory activity in the model reactions of thermal autooxidation of lard and hexadecane was studied. The rate constants of alkyl(hydroxylaryl)amines are the same as those of the corresponding alkylphenols, whereas the total inhibitory activity of some alkyl(hydroxylaryl)amines exceeds substantially that for alkylphenols.
