中文摘要:

      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 )/nBPA、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％.

英文摘要:

      The tetrabromobisphenol A was synthesized with acetonitrile as organic solvent from bisphenol-A,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)/n(BPA),temperature,the rate of oxidant.The production rate of bisphenol A can be up to 95.2% under given laboratory conditions.
