反応手順
A solution of 25 grams (0.1 mole) of 2,6-di-tert.butyl-4-methoxymethylphenol and one gram (0.015 mole) of KOH in 100 milliliters of methanol was heated to 60° C. 9 grams (0.125 moles) of isobutyraldehyde was added to the solution during a period of 10 minutes and the reaction mixture was heated under reflux for 3 hours. After the mixture had cooled to room temperature it was poured into 125 milliliters of 1% acetic acid. The solid that precipitated was filtered off and allowed to dry. There was obtained 28.5 grams (98.2% of theory) of 2,2-dimethyl-3-(3,5-di-tert.butyl-4-hydroxyphenyl) propionaldehyde with a melting point of 72° to 74° C.
