Versuchsvorschrift

To a 250 mL round bottom flask equipped with a reflux condensor was added 25 g of benzoic acid, 51 g of allyl alcohol, and 2.5 g of sulfuric acid. The mixture was heated at reflux for 17 hr, allowed to cool to room temperature, and 50 g of toluene was added. Using a 1 L separatory funnel, the mixture was washed once with 100 mL of water, once with 50 mL of 5 wt % Na2CO3 in water, and once more with 100 mL of water. The organic phase was dried over Na2SO4, filtered and distilled to yield allyl benzoate. The allyl benzoate distilled at a boiling point of 135° C. at about 60 mm Hg.
