โฆ Synopsis
The radical initiated addition of (3,5-di-tert. butyl-4-hydroxyphenyl)methane thiol (BHBM~ I, R = H) to olefins and its behaviour as an antioxidant are found to be complementary processes. In a system initiated by tert. butyl hydroperoxide (TBH), the adduct process is found to predominate for [BHBM]/[TBH] > 1 whereas radical trapping/peroxidolytic antioxidant reactions occur at molar ratios < 1. The antioxidanI species have been shown to be sulphur acids, eliminated from the oxidation products of I together with the corresponding sulphonic acid which is stable under the conditions of the reaction
