Versuchsvorschrift

Sodium p-hydroxybenzoate (64 g) and 51 g of benzyl chloride were added to 300 g of xylene, and 1.3 g of tetrabutyl ammonium chloride as a phase transfer catalyst and 2 g of methyl ethyl ketone were added. The mixture was refluxed for 8 hours Benzyl p-hydroxybenzoate was obtained in a yield of 73%, and the ratio of benzyl p-benzyloxybenzoate formed was 13%.
