Abstract
On the basis of bromopropyl-, mercaptopropyl- and allyl-substituted phenols, the synthesis of ω-[3-(4-hydroxyaryl)propylthio]alkalic acids was carried out. It was shown in the model reaction of methyl oleate autooxidation that the synthesized ω-[3-(3,5-di- tert-butyl-4-hydroxyphenyl)propylthio]alkanoic acids exceed phenosan antioxidant in the antioxidant activity due to the presence of sulphide groups in their structure.
