Synthesis and antiradical activity of hybrid antioxidants based on isobornylphenols

Аннотация

Alkylation of isobornylphenols with allylbenzene in the presence of homogeneous and heterogeneous catalysts of different nature has been studied. The maximum yield of phenols containing isobornyl and 1-phenylpropyl moieties has been achieved in the presence of catalyst FIBAN K-1 at 100°С and catalyst concentration of 10%. The inhibiting action of isobornylphenol derivatives has been studied in the model reaction of ethylbenzene oxidation. Hybrid antioxidants on the basis of isobornylphenols were found to actively interact with peroxide radicals and, therefore, they can be considered as promising additives for conservation of quality and increase in service life of different organic compounds and materials.
