Process for purification of propylene oxide

一种用于改进受聚氧化丙烯污染的氧化丙烯质量的方法，该方法包括以下步骤：(a)使液体氧化丙烯与由硅酸镁和/或硅酸钙组成的吸附剂接触，以使聚氧化丙烯的量降低到所需的水平；(b)回收纯化的氧化丙烯产物。 Process for improving the quality of a propylene oxide contaminated with poly(propylene oxide), which process comprises the steps of: (a) contacting the liquid propylene oxide with an adsorbent consist...
