Acetaldehyde → 2-Tert-butyl-6-[1-(3-tert-butyl-2-hydroxy-5-methylphenyl)ethyl]-4-methylphenol

Participants

Reaction Steps

Into the reactor described in the foregoing Example 1 there are charged 220 g (1.0 g-mol) of 2,6-ditert.butyl-4-methylphenol, 2.2 g of sulfuric acid and 44 g (1 g-mol) of acetaldehyde are fed into the reactor for one hour at the temperature of 125° C. On completion of the reaction, the reaction mass is treated following the procedure described in the foregoing Example 1 to give 124.6 g of 1,1,-bis-(5-methyl-3-tert.butyl-2-hydroxyphenyl)ethane which constitutes 96.4% of theory, as calculated for the reacted 2,6-ditert.butyl-4-methylphenol (conversion of the latter is 73%).
