MANUFACTURE OF 2,6-DITERTIARY BUTYL-4- MERCAPTOPHENOL AND 4,4-ISOPROPYLIDENEDITHIO- BIS(2,6-DITERTIARY BUTYLPHENOL)

摘要

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-hydroxyphenol)polysulfide with hydrogen gas in the presence of a catalytic amount of cobalt-molybdenum catalyst.
