摘要： Methods for removing methanol from acetone recycle streams during bisphenol-A production, thereby avoiding the deactivation of catalyst, by distilling an acetone-methanol-water comprising mixture such that acetone is taken overhead in form of a relatively pure distillate, and substantial portions of the methanol and the water are leaving with the bottom product.
摘要翻译： 在双酚A生产过程中从丙酮循环物流中除去甲醇的方法，由此通过蒸馏含有丙酮 - 甲醇 - 水的混合物使得丙酮以相当纯的馏出物的形式从头顶馏出，从而避免了催化剂的失活， 甲醇和水与底部产物一起离开。
