发明名称 Process for the removal of catalysts from polyether polyols employing water and adsorbent
摘要 An improvement in the process of catalyst removal in the preparation of polyether polyols is achieved by adding a critical amount of water from about 1 to about 5 percent by weight based on the weight of polyol to an adsorbent synthetic magnesium silicate-polyol mixture followed by filtration to remove the adsorbent.
