电气和电子废弃塑料中含有的溴化阻燃剂对人类和环境都有毒性。大多数溴化阻燃剂的处置技术对环境不友好。在这里，一种新的溶剂热过程被设计为从废弃的计算机外壳塑料中回收四溴双酚A，一种典型的溴化阻燃剂。采用溶剂热-真空旋转蒸发法处理废塑料。结果表明，四溴双酚A的回收率为78.9%，纯度为95.6%。核磁共振证实了四溴双酚A在溶剂热过程中的稳定性。动力学表明，整个聚合物层的扩散控制恢复。因此，溶剂热法是一种很有前途的回收电子电器废塑料中四溴双酚A的绿色方法。
Brominated flame retardants contained in electrical and electronic waste plastic are toxic to both humans and the environment. Most disposal technologies for brominated flame retardants are environmentally unfriendly. Here, a novel solvothermal process was designed to recover tetrabromobisphenol A, a typical brominated flame retardant, from waste computer housing plastic. The plastic waste was treated by the solvothermal process followed by vacuum rotary evaporation. Results show a tetrabromobisphenol A recovery efficiency of 78.9 %, and a purity of 95.6 %. The stability of tetrabromobisphenol A during the solvothermal process was confirmed by nuclear magnetic resonance. Kinetics showed that diffusion across the polymer layer controlled recovery. We conclude that the novel solvothermal process is a promising green way to recover tetrabromobisphenol A from electrical and electronic waste plastic.
