| titleOfInvention | A kind of preparation method of high-purity octabromoether |
| abstract | The invention relates to the technical field of chemical material synthesis, in particular to a method for preparing high-purity octabromoether. First, raw materials for bromination reaction, bromine, tetrabromoether, chloroform or dichloromethane, sodium sulfite and sodium carbonate, are prepared, and then Tetrabromoether is dissolved in dichloromethane or trichloromethane, then bromine is added, then a catalyst is added to the solution for bromination treatment, then sodium sulfite and sodium carbonate are added, and then water washing solution is added, and then uniformly stirred, and then Centrifugal treatment is carried out to make the liquid layered, and then the water washing liquid containing impurities is removed, and then the crystallization treatment is carried out by means of water crystallization, and finally the drying treatment is carried out to obtain high-purity octabromoether. The invention discloses a low-cost, The preparation method of high-purity octabromoether is that the tetrabromoether undergoes bromination reaction, and by adding a catalyst to react, and neutralizing the processes of water washing, crystallization, drying, etc., the technical effects of reducing environmental pollution, improving purity and reducing cost are realized. |
