Brief manufacture process:
By benzene, ethanol and hydrogen bromide derived. The benzyl alcohol was heated to 110 deg.] C, and slowly introduced hydrogen bromide, the reaction was refluxed. End of the reaction was cooled, washed successively with water, 10% sodium carbonate solution, washed with water. After drying over anhydrous potassium carbonate, vacuum distillation, collecting 97-99 ℃ (2.0kPa) distillate yield of 90%.
