Furfuryl acetate

Furfuryl acetate. Reflux a mixture of 39 2 g. (34-8 ml.) of redistilled furfuryl alcohol, 48 g. of glacial acetic acid, 150 ml. of benzene and 20 g. of Zeo-Karb 225/H in a 500 ml. bolt-head flask, using the apparatus described under iaoPropyl Lactate. After 3 hours, when the rate of collection of water in the water separator is extremely slow, allow to cool, separate the resin by suction filtration, and wash it with three 15 ml. portions of benzene. Remove the benzene, etc., from the combined filtrate and washings under reduced pressure (water pump) and then collect the crude ester at 74-90°/10 mm. a small sohd residue remains in the flask. Redistil the crude ester from a Claisen flask with fractionating side arm pure furfuryl acetate passes over at 79-80°/17 mm. The yield is 14 -5 g.

Saponification of the product with standard potassium hydroxide shows 93-94 per cent ester. It contains some fur-furyl alcohol, the removal of which by fractional distillation is difficult, because the boiling points of the alcohol (i6g°/752 mm.) and the ester (175°/764 mm.) are so close together. Furfuryl acetate darkens on standing. It may be redistilled with little loss to give an almost colorless product. 

D AIelio cioZ.242 converted furfuryl acetate into protoanemonin (59) and its dimer (anemonin) via several intermediates, which were not isolated.
