四溴双酚A的合成工艺改进

摘要

以乙腈为溶剂,在H2O2存在下,以双酚A、溴为原料制备了四溴双酚A,讨论了加料方式、搅拌速率、n(Br2 )BPA、反应温度、氧化剂的滴加速度等工艺条件对制取四溴双酚A产率的影响.在选定的实验条件下制取四溴双酚A的产率可达95.2％.%The tetrabromobisphenol A was synthesized with acetonitrile as organic solvent from bisphenolA, bromine and hydrogen peroxide. The influence on the production of bisphenol A was discussed by the way of feeding, stirring speed, the ratio of n(Br2)(BPA) , temperature, the rate of oxidant. The production rate of bisphenol A can be up to 95. 2% under given laboratory conditions.
