安全高效的四溴双酚A合成工艺

Safe and Effient Synthesis Process of Tetrabromobisphenol-A

以双酚A、溴素和双氧水为主要原料,以氯苯为主要溶剂,在20℃~25℃条件下通过原位溴化-氧化合成四溴双酚A。文章着重介绍了溴素双氧水同步滴加合成四溴双酚A的工艺以及与其它合成工艺相比较的优缺点。

With bisphenolA, bromine and hydrogen peroxide as the main raw material, chlo- robenzeneasthe as main solvent, tetrabromobisphenol - A was synthesized by in - situ bromination - oxidation under the condition of 25 ℃. It was introduced the synthesis of tetrabromobisphenol - A by synchronous drop addition as well as the advantage and disadvantage of compared with other syn- thetic process.
