ABSTRACT:
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 comprises reduction of bis (3,5-di-tertiarybutyl-4-hydroxyphenyl)polysulfide with hydrogen gas at a temperature range of from about 20.degree. C. to about 90.degree. C. in the presence of a catalytic amount of cobalt-molybdenum catalyst.
