Phenol → Phenyl benzoate

Reaction Conditions

Reaction Steps

A Claisen head was attached to a flask having an internal volume of 1000 ml, and a receiver having a gage was attached to the Claisen head via a condenser to make a distillation apparatus. Into this apparatus were charged methyl benzoate 100 g (735 mmole), phenol 553 g (5876 mmole) and titanium tetraisopropoxide 2.1 g (7.4 mmole). The contents were reacted with stirring at 190° C. in a bath. The reaction was conducted at atmospheric pressure, and the methanol thus produced was removed together with phenol. After reacting for 4 hours, excess phenol was distilled at atmospheric pressure. The remaining phenol and methyl benzoate were distilled under vacuum to obtain phenyl benzoate. The boiling point was 140° C./4mmHg. The yield was 108 g (74% yield in terms of methyl benzoate).
