Applications
Uses1-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.
Preparation methods
Preparation1-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%.
