Zusammenfassung: | The invention discloses a tetrabromobisphenol A intermediate layer material recycling and reusing process, and relates to the technical field of organic chemical industry wastewater treatment. Intermediate layer waste in the tetrabromobisphenol A synthesis process is collected in a unified mode, content analysis is conducted on components, the adding amount of bromine re-brominated is calculated according to the content of different brominated products, and after re-brominated, the tetrabromobisphenol A intermediate layer material is obtained. The qualified tetrabromobisphenol A is prepared. The bisphenol A, the monobromo bisphenol A, the dibromo bisphenol A and the tribromo bisphenol A in the materials of the middle layer are brominated into the tetrabromo bisphenol A, so that the waste materials of the middle layer generate economic benefits, the yield of the tetrabromo bisphenol A is increased, the hazardous waste treatment input is reduced, no potential safety hazard is generated to the ecological environ |
