用途有機合成の中間体。オクチル基の導入に使用する。
使用1-Bromooctane is used in organic synthesis. It is also used as an extraction solvent in the determination of volatile organic compounds present in water samples. Further, it is used in the preparation of quaternary ammonium chloride-modified poly(propylenimine) dendrimers.
製造方法1-Bromooctane is prepared by reacting octanol with hydrobromic acid. After the sodium bromide was completely dissolved with sulfuric acid, n-octanol was added, heated to reflux for 7-8 hours, cooled and diluted with water, the organic phase was separated, washed with water, concentrated sulfuric acid, water, and 10% sodium carbonate solution in turn, and washed with anhydrous sulfuric acid. Sodium dry. Distillation of 196-200°C, or 91-93°C (2.93kPa) fraction, is the finished product of 1-bromooctane. The yield is over 90%.
合成方法1-オクタノールに臭化水素酸を作用させる,または1-オクタノールに三臭化リンを作用させて合成する
純化方法Shake the bromide with H2SO4, wash it with water, dry with K2CO3 and fractionally distil it. [Beilstein 1 IV 422.]
