実験手順
Undecanol (14 g), 48% aqueous hydrobromic acid (30 g) and concentrated sulphuric acid (5 ml) are heated together under reflux for 51/2 hours. After cooling, water is added and the organic layer is separated, washed with concentrated sulphuric acid (20 ml), brine (50 ml) and dilute aqueous sodium carbonate (50 ml), and is then dried over calcium chloride. Distillaion under vacuum gives 1-bromoundecane (12 g) as a yellow oil, b.p. 60°-70° C./0.1 mm.
