실험 절차

36 g of 1,5-undecadien-4-ol is stirred and heated to reflux with 32.6 g of acetic acid anhydride for 1 hour. The excess anhydride and the resulting acetic acid are removed by distillation under reduced pressure. The residue is fractionated. Yield: 33.8 g (76%) 1,5-undecadien-4-yl acetate; b.p. 70°-80° C/2 Torr; n20D = 1.4468. 1,5-Nonadien-4-yl acetate was prepared in a similar way; yield: 75%; b.p. 85° C/10 Torr; n22D = 1.4403.
