  一种同时合成四溴双酚A单甲基醚和二甲基醚的制备方法

  摘要：

  本发明涉及一种同时合成四溴双酚A单甲基醚和二甲基醚的制备方法，将TBBPA溶于乙腈中，并用氢氧化钠去质子化，然后加入碘甲烷，加热发生甲基化反应，反应结束后冰浴冷却、二氯甲烷溶解清洗、过滤、除水并浓缩得到浓缩液，采用中压制备色谱对浓缩液进行分离提纯，即同时得到四溴双酚A单甲基醚和四溴双酚A二甲基醚；本发明仅通过一步反应即能同时获得TBBPA的单和二甲基醚，特别是保证了单甲基醚的高产率；同时本发明简化了后处理步骤，避免了现有方法中因多次萃取引起的损失；本发明中的中压制备色谱采用硅胶柱层析，适用于常量样品的提纯，且通过实时控制可以准确分离产物中的各组分，保证了产品的纯度。
