This invention relates to an improvement in a process for making 2,6-di-tertiarybutyl-4-mercaptophenol and 4,4'isopropylidenedithio-bis-(2,6-di-tertiarybutylphenol), which is effected by carrying out an electrocatalytic reduction of bis(3,5-di-tertiarybutyl-4-hydroxyphenol)-polysulfide at a lead cathode in an acidic electrolyte medium.
