    摘要: 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 consisting of magnesium silicate and/or calcium silicate under such conditions that the amount of poly(propylene oxide) is reduced to the desired level, and (b) recovering the purified propylene oxide product.
