The invention discloses a preparation method of 3-bromopropionitrile, which comprises the following steps: using acrylonitrile as a raw material, performing an intermolecular addition reaction of trimethylbromosilane, and then distilling and purifying to obtain high-purity 3-bromopropionitrile. The invention uses cheap acrylonitrile as a raw material, undergoes an intermolecular addition reaction of trimethyl bromide silane, and finally obtains high-purity 3-bromopropionitrile through distillation and purification. The raw materials are cheap and easy to obtain, suitable for commercial production, and environmentally friendly. The amount of three wastes is small and the yield is high. |
