Benzyl Alcohol → Benzyl 4-Hydroxybenzoate

Participants

Reaction Steps

152.1 g (1 mole) of methyl p-hydroxybenzoate, 216.2 g (2 moles) of benzyl alcohol and 0.304 g (0.4% based on the weight of methyl p-hydroxybenzoate) of dibutyltin oxide were fed into a four-necked glass flask, and reacted at 200° C. for 6 hours with stirring. Methanol which distilled out during the reaction was recovered for re-use in methyl esterification. After the reaction, the excess of benzyl alcohol was recovered under reduced pressure to give 221.6 g (yield 97.1%) of crude benzyl p-hydroxybenzoate. The ratio of benzyl p-benzyloxybenzoate formed was 1.1%.
