Acetic Anhydride → (E)-2-Nonenyl acetate

Participants

Reaction Steps

Pyridine (100 ml) and trans-2-nonen-1-ol (28.4 g, 0.2 mole) are heated to 110°C and acetic anhydride (30.6 g, 0.3 mole) is added dropwise. The reaction mixture is maintained at 110°-115° for 2 hours and 120°-125°C for 3 hours. The mixture is cooled and washed with water, 5% sulfuric acid, and finally water. The solution is dried over sodium sulfate. Trans-2-nonenyl acetate, 33.0 g is obtained by vacuum distillation, b.p. 70°-5°C/50-55 mm.
