production method | from the addition of α-chloropropene and hydrogen bromide, the α-chloropropene is sucked into the bromination tank, and a small amount of benzoyl peroxide is added, then the hydrogen bromide is introduced into the bottom of the tank, and the reaction temperature is controlled at 18 ° C. When the relative density is above 1.5, it is the end point. The product is washed with water and alkali (2% sodium hydroxide), then washed with water, the water layer is separated, dehydrated with anhydrous calcium chloride for 24h, and fractionated by regular pressure, and the low boiling substance below 130 ℃ is separated, then, distillation was performed under reduced pressure to collect a fraction above 70 ° C. (21.3kPa) to obtain a finished product. The hydrogen bromide used in the production is produced in the following way: hydrobromic acid is added to sodium bromide, the temperature is raised to 60 ° C. And sulfuric acid is added dropwise, and the reaction is maintained at 80-90 ° C. To give off hydrogen bromide gas. |
