一种低游离溴的十溴二苯乙烷制备方法

Preparation method of decabromodiphenylethane of low free bromine

Abstract

The invention relates to a preparation method of the decabromodiphenylethane of low free bromine, which effectively eliminates residual redundant free bromine by a twice distillation and ball-milling process and prepares the free bromine with low content less than or equal to 3 ppm and a decabromodiphenylethane product with high whiteness and good heat stability.
本发明涉及一种低游离溴的十溴二苯乙烷制备方法,本发明方法,通过采用二次蒸馏与球磨工序,有效去除残留多余的游离溴,制备游离溴含量为≤3ppm,游离溴含量低,且具有白度高,热稳定性好的十溴二苯乙烷产品。
