PROCESS FOR PREPARING 2,6-DI-TERTIARYBUTYL-4- MERCAPTOPHENOL AND 4,4'-ISOPROPYLIDENEDITHIO-BIS-(2,6- DI-TERTIARYBUTYLPHENOL) BY ELECTROCATALYSIS

摘要

ABSTRACTThis invention relates to an improvement in a processfor making 2,6-di-tertiarybutyl-4-mercaptophenol and 4,4'-isopropylidenedithio-bis-(2,6-di-tertiarybutylphenol),which is effected by carrying out an electrocatalyticreduction of bis(3,5-di-tertiarybutyl-4-hydroxyphenol)-polysulfide at a lead cathode in an acidic electrolytemedium.M01254
