Vorschrift

A mixture of 2-octanol (268.51 grams, 2.1 mol), AA (183.75 grams, 2.6 mol), p-toluenesulfonic acid monohydrate (5.00 grams, 26 mmol), toluene (250 grams) and phenothiazine (1.0 grams) was heated to reflux. Water was separated from the toluene/water azeotrope using a Dean Stark distillation trap. After six hours at reflux a total of 37 milliliters of water was collected in the trap. The reaction mixture was washed with 1 Molar aqueous sodium hydroxide (200 milliliters), then concentrated under reduced pressure. The remaining oil was distilled under reduced pressure (65-67° C. at 2 mmHg) to give the product as a colorless oil. (Yield: 248.6 grams)
