Methyl Acrylate → Methyl di-t-butyl hydroxyhydrocinnamate

Participants

Reaction Conditions

Reaction Steps

The reaction was heated to 140° C. to remove the water/toluene azeotrope. A white slurry was obtained and 7.2 g hazy toluene was collected in the trap. The Dean-Stark trap was removed and a cooling condenser was connected to the reactor. The heating was reset to 120° C. Vigorous condensation was observed and 99.1 g (1.15 mol) of methyl acrylate was added over a 45-minute period. After three hours of heating at 120° C., the 2,6-di-tert-butylphenol conversion was about 98.5% complete.
